In a manuscript there are two sections, the main part and the application part. For the main we use fourier package and for the application we use phv font with helvetica. The codes interfere with each other then. For example \Biggl(, \Biggr), \begin{cases} ... \end{cases} , \Biggl|, \Biggr| are not working for the fourier case. Also, \hbar is wrongly typed in the application part. Here is the code (given by AI) I am using % Configuration of \mathversion{application} (Helvetica / CM Math) \DeclareMathVersion{application} \SetSymbolFont{operators}{application}{T1}{phv}{m}{n} \SetSymbolFont{letters}{application}{OML}{cmm}{m}{it} \SetSymbolFont{symbols}{application}{OMS}{cmsy}{m}{n} \SetSymbolFont{largesymbols}{application}{OMX}{cmex}{m}{n} \SetMathAlphabet{\mathrm}{application}{T1}{phv}{m}{n} \SetMathAlphabet{\mathbf}{application}{T1}{phv}{b}{n} \SetMathAlphabet{\mathit}{application}{T1}{phv}{m}{it} % Dynamic Math Slot Switcher for Fourier <-> Application (Helvetica/CM) \makeatletter \let\fourier@orig@hbar\hbar % Fourier (normal) specific slots & delimiters \newcommand{\fourier@mathslots}{% \let\hbar\fourier@orig@hbar \global\mathcode`+ = "2280 \global\mathcode`- = "2200 \global\mathcode`= = "3281 \global\mathcode`< = "3282 \global\mathcode`> = "3283 % Delcodes for (, ), [, ], {, } \global\delcode`( = "0283A1 \global\delcode`) = "0293A2 \global\delcode`[ = "05B3A3 \global\delcode`] = "05D3A4 \global\delcode`\{ = "266328 \global\delcode`\} = "267329 % Macros for \lbrace, \rbrace, | \gdef\lbrace{\delimiter"4266328 }% \gdef\rbrace{\delimiter"5267329 }% \gdef\vert{\delimiter"026A30C }% \gdef\vertbar{\delimiter"026A30C }% } % Standard / Helvetica (application) slots & delimiters (CMEX/OMS) \newcommand{\standard@mathslots}{% \gdef\hbar{{\mathchar'26\mkern-9mu h}}% \global\mathcode`+ = "202B \global\mathcode`- = "2200 \global\mathcode`= = "303D \global\mathcode`< = "313C \global\mathcode`> = "313E % Delcodes for (, ), [, ], {, } \global\delcode`( = "028300 \global\delcode`) = "029301 \global\delcode`[ = "05B302 \global\delcode`] = "05D303 \global\delcode`\{ = "266308 \global\delcode`\} = "267309 % Macros for \lbrace, \rbrace, | \gdef\lbrace{\delimiter"4266308 }% \gdef\rbrace{\delimiter"5267309 }% \gdef\vert{\delimiter"026A30C }% \gdef\vertbar{\delimiter"026A30C }% } % Switch math slots when the math version changes \let\orig@mathversion\mathversion \renewcommand{\mathversion}[1]{% \orig@mathversion{#1}% \def\@tempa{#1}% \def\@tempb{normal}% \ifx\@tempa\@tempb \fourier@mathslots \else \standard@mathslots \fi } % Initialize in Fourier / normal mode \fourier@mathslots \makeatother Can you fix it so that two sections are working properly without interefering with each other? thanks.

Is it possible to set shape border rotate to a new default for a particular shape? For example, say I want to define a shape (which I'll call trapezoid in the MWE) that is essentially a trapezium but it is rotated by 180° by default. For example, \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{shapes.geometric} \pgfdeclareshape{trapezoid}{% \nodeparts{text}% \inheritsavedanchors[from=trapezium]% \inheritbackgroundpath[from=trapezium]% \inheritanchorborder[from=trapezium]% \inheritanchor[from=trapezium]{text}% \inheritanchor[from=trapezium]{center}% \inheritanchor[from=trapezium]{north}% \inheritanchor[from=trapezium]{south}% \inheritanchor[from=trapezium]{east}% \inheritanchor[from=trapezium]{west}% \inheritanchor[from=trapezium]{north west}% \inheritanchor[from=trapezium]{north east}% \inheritanchor[from=trapezium]{south west}% \inheritanchor[from=trapezium]{south east}% \behindbackgroundpath{% \pgfpathmoveto{\lowerleftpoint}% \pgfpathlineto{\upperrightpoint}% }% }% \begin{document} \begin{tikzpicture} \node [draw,trapezium,minimum size=1cm] {}; \node [draw=blue,trapezoid,minimum size=1cm,name=s] at (0,-1.25) {}; \node [draw=orange,trapezoid,minimum size=1cm,shape border rotate=180] at (0,-2.5) {}; % \foreach \anchor/\placement/\color in {north/above/orange,south/below/teal, % east/right/red,west/left/green,50/above/violet} % \draw [color=\color,shift=(s.\anchor)] plot [mark=x] coordinates {(0,0)}; \end{tikzpicture} but both the blue and the orange shapes should be the same. Alternatively, the blue one could be narrow-end-on-top, and the orange one rotates 180° more and looks like the black one. Options I have considered: Define a new shape and a new set of keys to go with it that are very similar to trapezium except upside-down (this is the worst option) Define trapezoid as a style that calls another shape (say, decorated trapezium or some such) whose only real purpose is to set another default value of shape border rotate Create an anchor that reads another key (say, trapezoid rotate) that determines what the user wants the new angle to be, then sets shape border rotate to something based on that. I am hoping there is another way, something like issuing \changepgfinitialvalue inside the shape definition so that the initial value changes for that shape (and only that shape). Is there?

I am preparing some physics exercises about pressure, and I would like to illustrate a rectangular box that can be placed on each of its three different faces. In this way, the same box would have three different base areas, while its dimensions remain unchanged. For example, my box has dimensions: 23 cm, 24 cm, 46 cm I would like to create the three possible orientations of the box with TikZ, so that in each drawing a different face is touching the ground. At the moment, I have this code for one orientation: \documentclass{article} \usepackage[margin=0.5in]{geometry} \usepackage{tikz} \begin{document} \begin{center} \begin{tikzpicture}[x=0.027cm,y=-0.027cm,line width=0.35pt,draw=black!75] \draw (77,123)--(77,199)--(146,231)--(281,163)--(281,110); \draw (146,156)--(146,231); \draw (212,55)--(212,122); \draw (77,123)--(60,84)--(126,117)--(146,156)--cycle; \draw (77,123)--(51,96)--(186,27)--(212,55)--(109,109); \draw (212,55)--(232,16)--(301,48)--(281,87)--cycle; \draw (146,156)--(281,87)--(319,91)--(184,160)--cycle; \draw[<->] (66,126)--(66,198); \draw[<->] (72,210)--(141,242); \draw[<->] (151,242)--(286,173); \node[rotate=-90,inner sep=0pt,font=\small] at (57,160) {23 cm}; \node[rotate=-25,inner sep=0pt,font=\small] at (101,233) {24 cm}; \node[rotate=27,inner sep=0pt,font=\small] at (227,213) {46 cm}; \end{tikzpicture} \end{center} \end{document} Is there a relatively simple way to modify this code (or to define a reusable TikZ command) so that I can obtain the other two orientations of the same box, with the 23 cm, 24 cm, and 46 cm dimensions exchanged accordingly? Ideally, I would like to be able to write something like \boxorientation{23}{24}{46} and obtain the corresponding drawing, or otherwise have a convenient way to generate the three possible orientations. The purpose is to use the drawings in physics exercises about pressure, where the students have to calculate the pressure exerted by the box when it rests on each of its three possible bases.

In their 1962 paper "The Braid Groups," Fox and Neuwirth use a notation similar to \veebar to describe one point being directly on top of another in the plane, as shown below. I was wondering what the best way to reproduce this in LaTeX would be. One option would be \stackrel\vee=, but it doesn't have quite the right spacing. (I wonder how they did it. Obviously this predates LaTeX, but I don't know enough about the way mathematics papers were typeset in the 60s. By the way, the terms "abscissa and ordinate" refer to the x- and y-coordinate respectively.)

Beginner Ipe user here! Every time I accidentally draw things in the wrong order my only method has been to redraw everything (eg. writing labels first and then drawing the filled nodes ultimately hiding the text labels as seen in the attached image). I was wondering if there was a way to make use of layers somehow to make this process simpler. I can see that you can toggle visibility but I could not see a way to change the pre-existing elements' stacking order. Are layers the way to go about it or is there some other tool I should be using for this? Thanks in advance & happy to add more clarification if necessary!

First, consider the code which produces the colored star: \documentclass{article} \usepackage{tikz} \usetikzlibrary{shapes.geometric} \begin{document} \begin{center} \begin{tikzpicture} \node[ shape=star, star points=5, star point ratio=2.5, minimum size=0.8cm, fill=red, draw=red ] {}; \end{tikzpicture} \end{center} \end{document} which produces: Now, consider the code which produces the tikz circle of asterisks: \documentclass{book} \usepackage{tikz} \usetikzlibrary{shapes.geometric} % Required for the star shape \usetikzlibrary{calc} \definecolor{oldgloryblue}{RGB}{10,49,97} \begin{document} \thispagestyle{empty} \begin{center} \begin{tikzpicture} \foreach \k in {0,30,...,360} \node at ($(0,0)+(\k:2)$){*}; \end{tikzpicture} \end{center} \end{document} and which produces However, when I replace the asterisk by `shape=star, star points=5, star point ratio=2.5, minimum size=0.8cm, fill=red, draw=red` I encounter many problems. QUESTION: How may I produce the circular image of `red stars' instead of the circular images of asterisks? Thank you.

I use the tasks environment from the tasks package to make exercises and solutions. If the solutions are long, there is a lot of free space since it seems that individual \tasks do not allow page breaks inside of them. Instead. the \task will start on the next page. I could just use the enumerate environment for these solutions, but some solutions are rather short, so I use the task envornment for these, to have multiple tasks side by side, going from left to right and not from top to bottom first. To have my code consistent, I would like to have the longer solutions in the task environment also. Can \tasks somehow be set up such that they can span over multiple pages?

I've been working on a fairly long document which uses quite a few subfiles. It had been compiling fine, but today I added some figures into one of the subfiles. Since then, when I try to compile the document it is like TeXworks gets stuck. The console output shows chapter headings and page numbers as I would expect, and seems to get to the end of the document. Then it says "*", and nothing else happens. It doesn't show any errors. I have also realised that it does create a PDF file in the right folder, but when I try to open that it seems to get stuck on loading (there's a grey background and a full loading bar, but no pages). I'm using MikTeX and TeXworks, set to compile using pdfLaTeX. Since there's no error message it's hard to know what's causing this. Does anyone know what's happening?

I am looking for a specific LaTex font which I loved very much (especially for the lambda it produces) I have already asked a question for the lambda but my preamble was restricted by my institution. But now I just want to use that lambda for my own documents. I'm attaching my previous questions and efforts here: Using lambda in different font than that of the document I want this document to recreate specifically. If anyone knows the font then please do let me know.

So I was playing around with latex2sympy2 - a Python library to convert LaTeX to SymPy objects. I tried to run this code: from latex2sympy2 import latex2sympy latex_code = r"\begin{bmatrix} a & b \\ c & d \end{bmatrix}" print(latex2sympy(latex_code)) and ran into this: Exception: I expected something else here \begin{bmatrix} a & b \\ c & d \end{bmatrix} ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^ It took me a while to figure out that the problem was d. I checked every letter instead of d and it worked correctly, run this so that you can see that yourself: from latex2sympy2 import latex2sympy for i in range(65, 91): if i == 69: continue # every letter except E print(chr(i), latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & %s \end{bmatrix}" % chr(i))) for i in range(97, 123): if i == 100: continue # every letter except d print(chr(i), latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & %s \end{bmatrix}" % chr(i))) # d try: print(latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & d \end{bmatrix}")) except Exception as e: print(f"{type(e).__name__}: {str(e)}") # E try: print(latex2sympy(r"\begin{bmatrix} 1 & 2 \\ 3 & E \end{bmatrix}")) except Exception as e: print(f"{type(e).__name__}: {str(e)}") I'm not good at LaTeX, though, please don't blame me. How do I fix that? I have no clues.

I'm trying to arrange a collection of nodes using \graph, which will be used to define a series of spath3 knot strands. However, the default cartesian placement strategy doesn't work very well for my purposes, as node chains that I intend to "tee off" from other nodes are placed at a constant width. It's possible to get what I want with the following code, but it's obviously rather fragile: \documentclass{article} \usepackage{tikz} \usetikzlibrary{graphs} \begin{document} \begin{tikzpicture} \graph[nodes={draw, as={}}]{ a -> b -> c, {[placement/width=1, placement/depth=1, grow down] b -> d -> f -> g}, {[placement/width=2, placement/depth=2, grow right] f -> p}, }; \end{tikzpicture} \end{document} How can I achieve the same effect by specifying the node rather than the width and depth?

There is a highly popular post from 2014 showcasing Nice scientific pictures show off but a lot has changed with LaTeX over the last 12 years. What is your best science picture to show off now that wasn't possible 12 years ago? Constraints for each answer: The Picture & Code: Show off a beautiful scientific illustration that utilizes features, packages, or engine capabilities (e.g., LuaLaTeX memory handling, modern pgfplots limits, Luametafun) that remove barriers which routinely stopped typical users from doing this 12 years ago (such as hard memory crashes, lack of default ecosystem support, or prohibitive manual workarounds). The Evolution: You must explicitly explain what technological progress or package developmentover the last decade made this picture possible today. AI usage is allowed, but must be acknowledged per community guidelines.

In the following minimal example, I placed each Arabic word on a separate line to make it clear that first the exclamation mark follows the fifth (final) Arabic word. Using "bidi=basic", the 5 Arabic words appear in the desired order (RTL), but that 1st excl.mark appears between the first Arabic word and the English word "There's", whereas it ought to appear between the word "Example:" and the fifth Arabic word (i.e. the excl.mark should be included within the RTL context of the Arabic phrase). \documentclass{article} \usepackage[english,bidi=basic]{babel} \babelprovide[onchar=ids fonts]{arabic} \babelfont{rm}{FreeSerif} \begin{document} \pagestyle{empty} \paragraph{Example:} يا ناس ما كان باس ! There's nothing wrong! \end{document} The placement is the same when I put the entire Arabic phrase on one line, with the excl.mark immediately after the last Arabic letter. I understand why this is happening. Is there a way to force that excl.mark to be included within the RTL scope of the Arabic phrase? (Edited to add: With all the Arabic on one line, most (all?) bidi-capable displays make the same mistake: the "default" LTR context causes the excl.mark to appear to the right of the Arabic phrase; usually this can be fixed by putting the Unicode RLE character U+202b in front of the first Arabic letter, and "Pop Directional Formatting" U+202c after the excl. mark. Doing that in the .tex file has no effect.)

Using LuaLaTeX for a text in English that includes Cantonese characters and their IPA transliteration, all works fine, except that one diacritic symbol used for some final consonants (P, T, K) merge with the following tone symbol. The result is unreadable. Here is the MWE: \usepackage[english]{babel} \usepackage{fontspec} \babelfont{rm}{TeX Gyre Pagella} \babelprovide[import=yue]{cantonese} \babelfont[cantonese]{rm}[Renderer=Harfbuzz]{Noto Sans HK} \babelfont[tipa]{rm}[Renderer=Harfbuzz]{FreeSans} \usepackage[dvipsnames]{xcolor} \DeclareRobustCommand\gdg[1]{\textcolor{CadetBlue}{\foreignlanguage{cantonese}{#1}}} \DeclareRobustCommand\gdgp[1]{\textcolor{MidnightBlue}{\foreignlanguage{tipa}{[\,{\footnotesize #1}\,]}}} \begin{document} This transliteration without the issue: \gdg{廣州} \gdgp{kʷɔːŋ² tsɐu¹} Here is one example of the problematic case: \gdg{百越} \gdgp{paːk̚³ jyːt̚⁶} \end{document} After compilation, the unreleased stop diacritic, also known as "combining left angle above", UNICODE U+031A, directly merges into the following tone number in superscript. Hence my question: is there a possibility to include a space that would apply only after this diacritic stop symbol and not before any tone number? Thank you in advance for any help or suggestion

I want to add some tagged section headings within frames with ltx-talk. It seems like using the exisiting section templates would be a neat way of doing this. But I am having trouble getting the section tagging structure to close correctly at the end of the frame. I can't find a way to inject sockets to close things without redefining internal ltx-talk macros. And so far, I haven't closed things correctly in all situations even if I do redefine. This seems to work in most cases I try, but seems risky: \cs_set_protected:Npn \__talk_frame_process:nn #1#2 { \__talk_decode_parse:n {#1} \bool_if:NT \l__talk_decode_mode_bool { \__talk_frame_process_aux:nn {#1} { #2 \par \UseTaggingSocket{sec/end}{6} \UseTaggingSocket{sec/end}{5} } } } What is a good way of doing this?

Let $G$ be a graph with vertex set $V(G)=\{1,2,\dots,n\}$ and edge set $E(G)=\{e_1, e_2,\dots,e_m\}$. We use the notation $i\sim j$ to mean that the vertices $i$ and $j$ are adjacent. The\textbf{\textit{ adjacency matrix}} of $G$, denoted by $A(G)$, is defined as $A(G)=[a_{ij}]_{n\times n}$, where \\ \\ \indent \indent \indent \indent \indent \indent \indent \indent \indent \indent $a_{ij}=\begin{cases} 1, & \text{if } i \sim j\\ 0, & \text{otherwise.} \end{cases}$ \\ \\ The \textit{\textbf{Laplacian matrix}} of $G$, denoted by $L(G)$, is defined as $L(G) := D(G)-A(G)$, where $D(G)$ is the diagonal matrix with degrees of the vertices of $G$ as diagonal entries. It is well-known that $L(G)$ is symmetric and positive semidefiniite and rank of $L(G)$ is $n-k$ where $k=k(G)$ is the number of connected components in $G$. Since $L(G)$ is symmetric and positive semidefinite so all the eigenvalues of $L(G)$ are real and non-negative. Moreover, $0$ is the smallest eigenvalue of $L(G)$ as for $v=(1 \ \ 1\ \dots \ 1)^T \in \R^n$, \ \ $L(G)v=0v$. \par Suppose that $0=\lambda_1\leq \lambda_2 \leq \cdots$ \section{Preliminaries} \section{Work done} Maximum 03 pages \section{Further study} Maximum 01 page \begin{thebibliography}{33} \bibitem{F1} Castelaz, A.~Commutivity degree of finite groups.~Thesis,~Department of Mathematics,~ Wake Forest University,~North Carolina,~5-8, 2010. \bibitem{C1} Cerf, V.,~Fernandez, E.,~Gostelow, K.,~and~Volausky, S.~ Formal control and low properties of a model of computation.

I want this lambda to use specifically: I have gone through many Tex exchange answers and AI answers but none of them work. Some of these are: How to make italic greek letter \lambda \usepackage{amsmath,amssymb} \usepackage{unicode-math} \setmathfont{Latin Modern Math} \setmathfont[range=\lambda]{TeX Gyre Termes Math} \DeclareSymbolFont{newtxletters}{OML}{ntxmi}{m}{it} \DeclareMathSymbol{\newtxlambda}{\mathord}{newtxletters}{"15} But either they throw an error or produces the same lambda as in produced before. So any help would be appreciated.

I would like to use forloop (or multido or another alternative if suggested) so that I can generate a series of short coding quizzes where each quiz uses verbatim (or fancyvrb or listings or another alternative). But when I try to do this: \documentclass{article} \usepackage{forloop} \newcounter{x} \begin{document} \forloop{x}{1}{\value{x} < 7}{% \begin{verbatim} def f(x): return x + 1 \end{verbatim} } \end{document} I get an error: File ended while scanning use of \@xverbatim The same basic problem has occurred when I have tried using multido rather than forloop; likewise fancyvrb or listings instead of verbatim. Is there anyway around this limitation?

I'm writing a lemma with italics font style where I need enumeration in lowercase Roman numerals.

Actually I want like this: Any help would be appreciated.
