I am trying to create a new math symbol. Could someone please help me with it? My current code: \documentclass[12pt]{report} \RequirePackage{tikz} \newcommand{\eq}{\begin{tikzpicture}% [scale=.175, line width=0.5pt] \draw (-1,1) -- (0,0); \draw (0,1) -- (-0.5,0.5); \draw (0,-1) -- (-1,0); \draw (-0.5,-0.5) -- (-1,-1); \end{tikzpicture}} \begin{document} \[ u - \eq - u \] \end{document} However, the symbol I am actually going for is this: I was using it for something like this:

I have the following code, where there are equations inside the table, formatted as inline with numbering: \documentclass{article} \usepackage{amsmath} \usepackage{booktabs} \usepackage{tabularx} \usepackage{cleveref} \usepackage{float} \begin{document} \begin{equation} P = P_0 + \rho g h \label{eq:pp0rhogh} \end{equation} \begin{table}[H] \centering \begin{tabularx}{\textwidth}{@{}l>{\centering\arraybackslash}Xr@{}} \toprule \textbf{Name} & \textbf{Equation} & \textbf{} \\ \midrule First & \(E = mc^2 \) & \refstepcounter{equation}(\theequation)\label{eq:emc} \\ Second & \(c = h\nu \) & \refstepcounter{equation}(\theequation)\label{eq:chnu} \\ \bottomrule \end{tabularx} \caption{Equations} \label{tab:equations} \end{table} \begin{equation} F = ma \label{eq:fma} \end{equation} \eqref{eq:pp0rhogh}, \eqref{eq:emc}, \eqref{eq:chnu}, \eqref{eq:fma}, \cref{tab:equations} \end{document} Output: What I want is proper hyperref anchoring. I tried the following: First & \(E = mc^2 \) & \refstepcounter{equation}\phantomsection(\theequation)\label{eq:emc} \\ Clicking on \eqref{eq:emc} results in the following output, which is not as expected, the anchor is not in the correct position. Output: I also tried: Second & \(\displaystyle c = h\nu \refstepcounter{equation}\phantomsection{\theequation}\label{eq:chnu}\) & (\ref{eq:chnu}) \\ Clicking on \eqref{eq:chnu} works correctly results in the following output with the hyperlink, but the output shows c = h \nu 3, I do not want to have the extra number 3, and the equation number (3) at the end of the line should not be clickable. Output: Whole code: \documentclass{article} \usepackage{amsmath} \usepackage{booktabs} \usepackage{tabularx} \usepackage{float} \usepackage{caption} \usepackage[colorlinks]{hyperref} \usepackage{cleveref} \begin{document} \begin{equation} P = P_0 + \rho g h \label{eq:pp0rhogh} \end{equation} \begin{table}[H] \centering \begin{tabularx}{\textwidth}{@{}l>{\centering\arraybackslash}Xr@{}} \toprule \textbf{Name} & \textbf{Equation} & \textbf{} \\ \midrule First & \(E = mc^2 \) & \refstepcounter{equation}\phantomsection(\theequation)\label{eq:emc} \\ Second & \(\displaystyle c = h\nu \refstepcounter{equation}\phantomsection{\theequation}\label{eq:chnu}\) & (\ref{eq:chnu}) \\ \bottomrule \end{tabularx} \caption{Equations} \label{tab:equations} \end{table} \begin{equation} F = ma \label{eq:fma} \end{equation} \eqref{eq:pp0rhogh}, \eqref{eq:emc}, \eqref{eq:chnu}, \eqref{eq:fma} \end{document} Output:

For a class of mine, I'm in the process to switch from ntheorem to keytheorems but, for compatibility reason, I would like to make the output of “theorems” as identical as possible. Unfortunately, it is not the case, as shown in the following M( non realistic )CE: \RequirePackage{comment} \includecomment{kt}\excludecomment{nt} % \includecomment{nt}\excludecomment{kt} \documentclass{article} \usepackage[ textwidth=12.75cm, paperwidth=14cm, paperheight=2cm, showframe ]{geometry} \begin{kt} \usepackage{keytheorems} \newkeytheoremstyle{rmk-style}{ inherit-style=definition, notefont=\bfseries, headpunct={~--} } \newkeytheorem{rmk}[style=rmk-style,name=Remark] \end{kt} \begin{nt} \usepackage{ntheorem} \theoremstyle{plain} \theoremheaderfont{\normalfont\bfseries} \theorembodyfont{\normalfont} \theoremseparator{~--} \theoremsymbol{} \newtheorem{rmk}{Remark} \end{nt} \begin{document} \begin{rmk}[Euler's identity] One of the most beautiful mathematical equation: \[ e^{i\pi}+1=0 \] \end{rmk} \end{document} As it is (keytheorems in force), the output is the following: whereas, if the second line is commented and the third one is uncommented (ntheorem in force), the output is the following: How could I configure keytheorems in order it produces the same output as ntheorem?

I'm trying to read a simple csv into a datatool database and then populate a table with this data. The persistent error is reported as "Package datatool error: Database 'gradesDB doesn't exist' in the TeXworks console output. I'm using the current TeXworks 2025 full/complete installation. The csv was encoded as uft-8. This csv file is named data.csv (NOTE: In the preview of this post this file appears in a single row format. It is actually written as a 4 row x 3 column form with the first three rows terminated by CRLF) Name,Surname,Grade Albert,Einstein,147 Marie,Curie,159 Thomas,Edison,179 I've consulted online AI and version 3.4.3 2025-12-04 of The Datatool Bundle: Databases and Data Manipulation from Dickimaw Books for documentation. This package is new to me and I have a feeling is there is a simple error I'm not catching. I greatly appreciate any help you might offer.

I am trying to use text in a particular font (in this case, a Helvetica clone) without bringing on an entire package and/or forcing the user to use a particular package. A minimal example is below: \documentclass{article} \usepackage{tikz} \begin{document}\noindent This is document text. \begin{center} \begin{tikzpicture} \begin{scope}[every node/.style={transform shape}] \renewcommand*{\sfdefault}{phv} \node {\resizebox{!}{0.5cm}{\sffamily WOOHOO!}}; \end{scope} \end{tikzpicture} \end{center} This is more document text. \end{document} However, I get different results with different engines, as shown: My questions: (1) why doesn't LuaLaTeX show the same result as PDFLaTeX? (2) What is the "right" (read: most portable) way to include a single piece of Helvetica (or some other font) in this manner without dragging in an entire package or forcing the use of a particular TeX engine?

Here are two different bits of code that difer by exactly one letter: Number 1: \documentclass{amsart} \usepackage[all]{xy} \begin{document} \begin{displaymath} \xymatrix{ { \begin{tabular}{c|c} \hline $x_2$ & 7 \\ \hline $x_3$ & 4 \\ \hline \end{tabular} } \ar@(ul,dl)[]_{\pi^0} } \end{displaymath} \end{document} Number 2: \documentclass{amsart} \usepackage[all]{xy} \begin{document} \begin{displaymath} \xymatrix{ { \begin{tabular}{c|c} \hline $x_2$ & 7 \\ \hline $x_3$ & 4 \\ \hline \end{tabular} } \ar@(l,dl)[]_{\pi^0} } \end{displaymath} \end{document} The difference is that in number 2, the arrow is modified with @(l,dl) while in number 1 it is modified with @(ul,dl) Number 1 doesn't compile. Number 2 does but looks ugly. I'd like Number 1 to compile and look better than Number 2 in the way it should. Since I know it will come up: no, I'm not willing to switch to tikz. Yes, I know tikz is better. But I know the syntax for xypic and have been using it for sneaking up on twenty years and I just turned 40 and am thus officially allowed to be a stick in the mud about things.

I tried all answers in Spacing around \left and \right and none of them work. I use code generate by computer CAS. And all the code generates \left(...\right). So not possible to do any manual editing of latex code generated. Only issue is that something like f\left(x\right) adds extra space between function name f and the parentheses. I am not talking about any space inside parentheses, but the space outside between function name and starting (. I only want this space to be the same as if code was written using f(x). Nothing else change. First, here is MWE showing the issue \documentclass[12pt]{article} \usepackage[T1]{fontenc} \usepackage{kpfonts,baskervald} \usepackage{amsmath} \begin{document} \begin{align*} \int \frac{dy}{g(y)} &= \int f(x) \, dx\\ \int \frac{dy}{g\left(y\right)} &= \int f\left(x\right) \, dx \end{align*} \end{document} Compiled with lualatex gives Notice how the space after function name is larger when using \left(...\right) which is the second equation.

The fontsetup package provides with a \convolution operator command to access a big star symbol from the New Computer Modern fonts. However, fontsetup works only with XeLaTeX and LuaLaTeX. How does one access this glyph from the NewCM fonts with OpTeX? The \convolution command is defined in fspdefault.tex as \DeclareMathOperator*{\convolution}{\mathchoice{\char"E037}{\char"E036}{\char"E038}{\char"E039}}. The question essentially asks about using glyphs not encoded their Unicode slots (Private Use Areas?), as a Unicode slot for the glyph does not exist. LuaLaTeX MWE: \documentclass{article} \usepackage[newcmbb]{fontsetup} \begin{document} \[ \convolution_{1\le i\le n} a_i \] \[ \sum_{i=1}^n \convolution_{i=1}^n x_i \qquad \textstyle \sum\convolution_{i=1}^n x_i \qquad \scriptstyle \sum\convolution_{i=1}^n x_i \qquad \scriptscriptstyle \sum\convolution_{i=1}^n x_i \] \end{document}

How can I display the intersection of the following two surfaces in LaTeX? I have used the following codes as a default but I am not getting acceptable output.

How can I read out numbers from a list, say \def\pList{0.1, 1/6, 0.25, 0.4} (or array, say \def\pListArray{{\pList}}), with xint? Background: I want to keep fractions, like 1/6 in it's original form (not decimal value 0.1666 here). On the other hand, I need to calc 1-<value> too, and I want, in the case of 1/6 the value 5/6 (=1 - 1/6). I have a main document with a lot of xint content and calculations; therefore, for consistency reasons, it should be done with xint (it's clear that there are other packages or methods for this); and: There must be a method in the xint-package that I can't find in the manual. Does anybody know? \documentclass[margin=5pt, varwidth]{standalone} \usepackage{tikz} \usepackage{xintexpr} \begin{document} \def\pList{0.1, 1/6, 0.25, 0.4}% List \def\pListArray{{\pList}} \section{The pList} \pList \section{pgfmath-test for fraction-readout (bad)} p=\pgfmathprint{\pListArray[0]}, q=\pgfmathprint{1-\pListArray[0]} good. But p=\pgfmathprint{\pListArray[1]}, q=\pgfmathprint{1-\pListArray[1]} bad. \section{xint-test for fractions (good), but how to readout?} p=\xinteval{1/6}, q=\xinteval{1-1/6} \end{document}

I know that I can make circular diagrams with the nice smartdiagram package, but arrows do not fit perfectly in a imaginary circle. In fact, the diagram is far from a circle when there are only two or three nodes: \documentclass{standalone} \usepackage{smartdiagram} \begin{document} \smartdiagramset{ connection color=red, module shape= circle, circular distance=2cm, uniform color list=white for 6 items, uniform arrow color=true, arrow color=black} \smartdiagram[circular diagram:clockwise]{foo, bar} \end{document} I know also that there are several examples in this site about making circular diagrams without this package, but translating these examples to diagrams with a different numbers of nodes is complex, so I tried an automated solution with tikz (without really knowing what I was doing, I have to admit) so that I only have to modify a list of nodes in \mylist and little more to obtain the result: \documentclass[border=2mm]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[ > = Stealth, every node/.style = {circle, draw, thick, minimum width=1cm, align=center} ] \def\mylist{foo, bar, baz} % play with this \foreach \x [count=\i from 1] in \mylist {\xdef\n{\i}} \def\radio{2cm} % and this if needed \foreach \texto [count=\i from 0] in \mylist{ \pgfmathsetmacro\ang{-\i*360/\n} \node (n\i) at (\ang:\radio) {\texto}; } \foreach \dummy [count=\i from 0] in \mylist{ \pgfmathsetmacro\j{int(mod(\i+1,\n))} \pgfmathsetmacro\angini{-\i*360/\n} \pgfmathsetmacro\angfin{-\j*360/\n} \pgfmathsetmacro\outang{mod(\angini - 90 + 720, 360)} \pgfmathsetmacro\inang {mod(\angfin + 90 + 720, 360)} \draw[->, thick, line width=1.4pt] (n\i) to[out=\outang, in=\inang, looseness=.9] (n\j); % and with the looseness } \end{tikzpicture} \end{document} Mainly it works. The problem is that like in smartdiagram, the arrows don't perfectly follow an imaginary circle, that was the idea behind getting involved in this business. Playing with looseness is possible to correct a bit the curvature of the arrows, but it's tedious and the result is never perfect. So, the result should be ideally near to the image below (that I modified manually in Inkscape) and still require minimal settings to adapt the code to diagrams of n nodes. Fixes of the MWE as well as alternative approaches are welcome. Edit Thank you all for the excellent suggestions. This time, I am truly sorry I can only accept one.

Using the code adopted from this answer, I am able to modify the position and width of \check, \widehat, etc. for various math characters (as a first step towards answering this earlier question). However, as one can see, the letters are not "centered" in the bounding box. As a result, the spacing between different letters and symbols appears strange. (For example, to make the symbols on top placed at right place, I have to move the letters via xoffset, but then its position relative to the bounding box is not quite appropriate.) With the keywords known to me as in that answer, it seems one could only move the letter, but not its bounding box. Is there some other keywords one could use in order to have more control over this situation? (Actually, just out of curiosity, may I also ask where can one find a list of available keywords/switches that can be tweaked?) Below is a MWE. \documentclass{article} \usepackage{kpfonts-otf} \usepackage{unicode-math} \usepackage{luacode} \begin{luacode*} local adjustments = { ["Asana-Math.otf"] = { ["𝐿"] = { xoffset = 0.03, -- yoffset = -0.5, width = 0.75, -- height = 0.5, -- depth = 0, }, ["𝑀"] = { xoffset = -0.05, -- yoffset = -0.5, width = 0.9, -- height = 0.5, -- depth = 0, }, ["𝑁"] = { xoffset = -0.05, -- yoffset = -0.5, width = 0.9, -- height = 0.5, -- depth = 0, }, } } do local data = io.loaddata(kpse.find_file("font-cff.lmt")) data = data:gsub("<const>", ""):gsub("pack_result_tagged =", "fonts.handlers.otf.pack_result_tagged =") load(data, "font-cff.lua", "t", luaotfload.fontloader)() end luatexbase.add_to_callback( "luaotfload.patch_font", function(tfmdata, specification, font_id) local path = tfmdata.specification.filename local filename = file.basename(path) local by_filename = adjustments[filename] if not by_filename then return end tfmdata.streamprovider = 1 local size = tfmdata.size local units_per_em = tfmdata.units_per_em for character, adjustment in pairs(by_filename) do local codepoint = utf8.codepoint(character) local index = tfmdata.characters[codepoint].index local character = tfmdata.characters[codepoint] local shapes = fonts.hashes.shapes[font_id].glyphs local streams = fonts.hashes.streams[font_id].streams local original_shape = shapes[index] local new_stream = fonts.handlers.otf.pack_result_tagged( original_shape.segments, original_shape.width, (adjustment.xoffset or 0) * units_per_em, -(adjustment.yoffset or 0) * units_per_em ) streams[index] = new_stream for _, dimen in pairs { "width", "height", "depth" } do if adjustment[dimen] then character[dimen] = adjustment[dimen] * size end end end end, "rewrite-characters" ) \end{luacode*} \setmathfont{Asana-Math.otf}[range={it/{Latin,latin},bfit/{Latin,latin},up/num,bfup/num}] \begin{document} \[ \check{L} \check{M} \check{N} \] \[ \widehat{L} \widehat{M} \widehat{N} \] \[ \widetilde{L} \widetilde{M} \widetilde{N} \] \fbox{\( L \)} \fbox{\( \check{L} \)} \fbox{\( \widehat{L} \)} \fbox{\( M \)} \fbox{\( \check{M} \)} \fbox{\( \widehat{M} \)} \fbox{\( N \)} \fbox{\( \check{N} \)} \fbox{\( \widehat{N} \)} \end{document}

The question is rather simple. How to obtain the following big asterisk symbol? I apologize if it is duplicate. Thank you very much.

What I’m trying to accomplish is best illustrated as follows: The first line (“Monday, December 22, 2025, 16:00 EST”) is right-aligned to the text width (possibly by \hfill, but not a hard requirement). The second line (“New York City, New York”) needs to be left-aligned to the left edge of that first line. In other words, the start of the M in “Monday” and N in “New York” are vertically aligned. How can this be done?

For certain (math) font configurations, the result generally look nice but occasionally may produce slightly unpleasant visual result. For example, for \widehat, \widetilde and \check: It would seem that they are not properly centered for certain letters (B, C, E, F, G, H, K, M, N, etc.), and the width is also not quite uniform, compared with visual expectation. Things like this would usually be better fixed directly on the font level. However, before the font got fixed, I know that there exists Lua code that can (manually and temporarily) edit the kerning of math characters, for example, space between letters, space between letter and subscripts/superscripts, etc. Could the same kind of code also modify/redefine the center, the baseline, the character width, etc.? More precisely, I would like to make use of Lua code to adjust the positioning of those symbols (\check, \widehat etc.) on top of the letters (center, and possibly height), and then if possible, also to adjust the (virtual) width of these symbols, so as to make the width of these symbols more pleasant. Hopefully this could be achieved by similar code as below, I just don't know where to find the correct keywords/switches. Here is the lua code I adopted some time ago from this answer that can modify the kerning between letter and scripts. For modifying kerning between symbols, one could see, e.g., this answer. (Unfortunately I do not quite understand how these code work, for example if I change topright to top in wish to change the relative position for hats and tildes, it actually does nothing effective, so this is clearly not the right keyword/switch to use...) Also, I wonder if these lua code can be combined, for example, if I simply put the code for adjusting kerning between symbols/letters inside the code below (within local mathkerns = ...), then nothing effective happens... \directlua { local mathkerns = { ["Asana-Math"] = { [0x1D439] = {% F topright = { {height=0,kern=30}, }, }, [0x1D443] = {% P topright = { {height=0,kern=90}, }, }, [0x1D447] = {% T bottomright = { {height=0,kern=-120}, }, }, [0x1D449] = {% V bottomright = { {height=0,kern=-120}, }, }, [0x1D44A] = {% W bottomright = { {height=0,kern=-30}, }, }, [0x1D453] = {% f bottomright = { {height=0,kern=-135}, }, }, [0x1D44F] = {% b topright = { {height=0,kern=75}, }, }, }, } local function initmathkern(tfmdata) local values = mathkerns[tfmdata.properties.psname] if not values then return end for cp, value in next, values do local tcp = type(cp) if tcp == 'string' then cp = tfmdata.resources.unicodes[cp] end local char = tfmdata.characters[cp] if char then local mathkern = char.mathkerns if not mathkern then mathkern = {} char.mathkerns = mathkern end for corner, v in next, value do mathkern[corner] = v end end end end fonts.constructors.newfeatures'otf'.register{ name = 'mathkern', description = 'Overwrite mathkern values', initializers = { base = initmathkern, }, } } Here is a MWE. \documentclass{article} \usepackage{kpfonts-otf} \usepackage{unicode-math} \setmathfont{KpMath-Sans.otf}[range={\check}] \setmathfont[RawFeature=mathkern]{Asana-Math.otf}[range={it/{Latin,latin},bfit/{Latin,latin},up/num,bfup/num}] \begin{document} \[ \check{A} \check{B} \check{C} \check{D} \check{E} \check{F} \check{G} \check{H} \check{I} \check{J} \check{K} \check{L} \check{M} \check{N} \check{O} \check{P} \check{Q} \check{R} \check{S} \check{T} \check{U} \check{V} \check{W} \check{X} \check{Y} \check{Z} \] \[ \widehat{A} \widehat{B} \widehat{C} \widehat{D} \widehat{E} \widehat{F} \widehat{G} \widehat{H} \widehat{I} \widehat{J} \widehat{K} \widehat{L} \widehat{M} \widehat{N} \widehat{O} \widehat{P} \widehat{Q} \widehat{R} \widehat{S} \widehat{T} \widehat{U} \widehat{V} \widehat{W} \widehat{X} \widehat{Y} \widehat{Z} \] \[ \widetilde{A} \widetilde{B} \widetilde{C} \widetilde{D} \widetilde{E} \widetilde{F} \widetilde{G} \widetilde{H} \widetilde{I} \widetilde{J} \widetilde{K} \widetilde{L} \widetilde{M} \widetilde{N} \widetilde{O} \widetilde{P} \widetilde{Q} \widetilde{R} \widetilde{S} \widetilde{T} \widetilde{U} \widetilde{V} \widetilde{W} \widetilde{X} \widetilde{Y} \widetilde{Z} \] \end{document}

I would like to produce a Ȟ ("H" with caron accent) in math mode, specifically, for \mathsf. (This is an uncommon notation used for Čech cohomology in a book.) Perhaps this would be easy for pdfLaTeX. However, when using LuaLaTeX, and when this character is not already provided in the font, I can only get very strange output: Is there some way to mimic this caron accent in this situation? More generally, how can one apply this accent to general math symbols? (In the same book, this accent seems to be used to represent the dual objects, e.g., V with caron accent instead of V^{\vee}, possibly to save some space...) (I tried \check, but it looks different and cannot be properly aligned...) \documentclass{article} \usepackage{kpfonts-otf} \usepackage{unicode-math} \begin{document} Ȟ % \v{H} \( \mathsf{Ȟ} \) \( \mathsf{\v{H}} \) \( \check{\mathsf{H}} \) \end{document}

I am using the package metre. It has the environment \metra{} used for typesetting latin (and greek) metre notation. This environment has almost all the special characters I need, except one: I need a character that looks somewhat like a fermata 𝄐 but preferrably in the same style as the other metrical symbols. This could, I believe, be achieved by simply taking the character breve that is produced by \documentclass{article} \usepackage[en]{metre} \begin{document} \metra{\a\m\b\bm} \end{document} and have it flipped upside down and a dot put underneath. In a book, this is what it looks like: It's the last symbol of each of the lines in the box. Does anyone know how this could be achieved? I even tried contacting the package's creator but his email address does not seem to exist anymore. My MWE produces the symbols in this picture (the ones inside the brackets): Thanks in advance!

(Sorry again for the vague title of this question (which is a follow-up of another question of mine), I can't think of a more appropriate one.) Suppose I'd like to augment the key set of keytheorems with a Title key which isn't exactly an alias of its title (or its alias name) key but which makes uppercase the first character of its value before passing it to keytheorems' title (or name). In the following MCE, I rely for this on an auxiliary token list which, unfortunately, is not limited to the definition of each defined theorem: only the last value it took is used each time one of the defined theorems is used, so instead of: Abc 1.

glossaries allows one to include text between an acronym and its long-form spell-out in parentheses like this: The \gls{abc}['s] collation This prints as: The Alphabet’s (ABC) collation However, is it possible also to include arbitrary text in the parentheses, not necessarily on first use (as with \gls above; I know there's the key first={} in definitions), but also more generally using \acrfull? This is to avoid e.g. something like The Alphabet (ABC) (cf. John Doe 1985) in favour of The Alphabet (ABC; cf.

As a physicist, I often need to typeset tensor indices where it matters whether the subscript is to the left or to the right of the superscript. My usual solution is to use {t_A}^B, which puts the superscript B to the right of the subscript A, compared to t_A^B which puts the superscript B vertically aligned with the subscript A. However, I recently noticed that if I use \bar{t} or \tilde{t} instead of t above, the output no longer differs whether I enclose the (xxx)_A part with braces or not. But, \overline{t} still behaves as I expect. Then I tried \widetilde{t}, which still ignores the braces. Is this a bug or a feature? If it's a feature, how should I classify which commands ignore the braces and which do not? In particular, is there a "tilde" command that behaves like \overline that can put the superscript to the right of the subscript? Minimal working example: \documentclass{article} \begin{document} \begin{equation} \begin{array}{lllll} t_A^B & \tilde{t}_A^B & \widetilde{t}_A^B & \bar{t}_A^B & \overline{t}_A^B \\ {t_A}^B & {\tilde{t}_A}^B & {\widetilde{t}_A}^B & {\bar{t}_A}^B & {\overline{t}_A}^B \end{array} \end{equation} \end{document} Output:
