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

I want to do something like this : display binary operation evaluation in different ways (decomposing the binary evaluation in two unary evaluation, etc) with a much simple syntax, i.e. : Here I use postfix and infix notation for function applications, for example : in row 7 of this table, (c1 → c2) can be decomposed into c2 (c1 → _) , in which (c1 → _) is the first unary application (marked with blue framed box), c2 (c1 → _) is the second one (marked with blue framed box); and Homo stands for the Hom functor, Expo stands for Exponent operation in Cartesian Closed Category. However the compilation tooks so much time, I think I use too much \csname...\endcsname, \@ifnextchar and so on. Seeking for better solution like expl3 or LuaLaTeX. The main code for this syntax is written inside layouts_custom/set_math_evl02.tex in the overleaf MWE project.

I don't know what this is called to ask the question better. I'm trying to match an old book's structure as close as possible and it has multiple small labels within the same paragraph that are floated left and that also serve as sections in the right-hand page headers only but not in the TOC. An example is provided below; however, in the book, the text is not split/broken before a block item, it just runs continuous around each. I tried using \placefigure but either that is the wrong approach or I did it wrong. I'd like the second line,immediately before Block 1, to be justified and the line before Block 2 to not break at "around" but continue with the next line's "multiple". Is it possible and, if so, what's it called so I can look it up? Thank you. \setuplayout[width=5in] \starttext An example of a fairly old handset document that includes justified text wrapped around mulitple blocks of text that are set to the left. \placefigure[none,left,paragraph][]{}{\framed{Block 1}}And each one of these blocks that are sort of floats is also a section in the sense that which ever block is on the right-hand page appears in that page's header. To repeat that, this is an example of a fairly old handset document that includes justified text wrapped around \placefigure[none,left,paragraph][]{}{\framed{Block 2}}mulitple blocks of text that are set to the left.

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?

in the following code and in the attached image, the graph becomes misaligned.

I'm creating a math worksheet for my Algebra 2 students with a two-column problem layout using longtable. I'm experiencing two related spacing issues with my step by step solutions layout: Inconsistent spacing before solution steps: Problems 1-4 (outside longtable) have tight spacing between the problem statement and solution steps, while problems 5-8 (inside longtable) have much larger spacing before the solution steps. Answer boxes crowding next row: In the two-column section, answer boxes at the bottom of cells are too close to the problem statements in the next table row. What I've tried: Adjusting \par\vspace values (made page 1 worse) Using \vskip instead of \par\vspace (broke page 1 alignment) Modifying \arraystretch and \extrarowheight (affected all rows uniformly, not the issue) Question: How can I achieve consistent vertical spacing before the solutionsteps environment both inside and outside longtable, while preventing answer boxes from crowding the next table row?

Some LaTeX packages provide nice functionality to compute the optimal margins for a given page size, font and font size. I.e. KOMA-Script does offer the package option DIV=calc and \KOMAoptions{DIV=last}. This, however, leads to rather large margins, if A4 paper is used. I was hence wondering if we can even go one step further and let LaTex also compute the "optimal" paper size (if such a thing exists, but I'm certain that typographers have opinions on this) based on font/font size and the number of columns we use. Of course, this means that if we print the output, we need to cut/trim the paper accordingly.

I am writing a document that can be read and shared freely, but not modified one bit. I want it to "break" once it's sha256 key differs or at least, indicate that it has been changed over time. I have come across this question: It is possible to lock up pdf? where it says it is a duplicate of: Digital signature, where the solution is this link: https://answers.onstartups.com/questions/41625/protecting-works-for-being-able-to-prove-later-ive-done-this-on-this-date that seems broken. I am also aware of digsig which seems more like adding the image of a signature rather than actually generating crytographic keys, etc. I see other stuff like using qpdf and secondary software solution. I wondered if it were possible to do this natively using lualatex? I am using Linux Mint and LuaHBTeX, Version 1.22.0 (TeX Live 2025) I am sorry I have no working example to offer because I'm not even sure where to start. I apologise in advance for my rule-breaking.

I’m dissatisfied with the formal letter templates on Overleaf and, frankly, with most of the tutorials I’ve found online. I genuinely enjoy written correspondence, and I want my formal letter format to look truly professional. I’ve created my own template for a confidential formal letter based on what I remember from past training, but it’s been a long time. I’d appreciate feedback to help ensure the format looks polished and professional. I did not know what tag to use, so I used layout.

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?

I am trying to use \setkomafont to set the font of titles and headings, but when I try to use a custom font with \fontspec or \fontfamily, it overrides \bfseries instead of applying them both. So, when I use the command below, it only applies Roboto and the font size: \setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\bfseries\selectfont} Other similar commands that I have tried but didn't work: \setkomafont{title}{\fontfamily{Roboto}\fontsize{20}{24}\bfseries\selectfont} % \setkomafont{title}{\fontfamily{Helvetica}\fontsize{20}{24}\bfseries\selectfont} % \setkomafont{title}{\fontfamily{Montserrat}\fontsize{20}{24}\bfseries\selectfont} % etc, etc When I use each of these commands alone, it also works fine \setkomafont{title}{\fontsize{20}{24}\bfseries\selectfont} % and \setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\selectfont} As expected, the first command applies the bold font and the second command applies the Roboto font. A non-exhaustive list of l tried trying to fix this problem (we're just going to use \fontspec{Roboto} in all of them for simplicities sake I've gone insane enough. Just know that I tried many fonts in both koma-script and fontspec): \setkomafont{title}{{\fontspec{Roboto}}\fontsize{20}{24}\bfseries\selectfont} \setkomafont{title}{{\fontspec{Roboto}}\fontsize{20}{24}\bfseries\selectfont} % \setkomafont{title}{\fontspec{Roboto}{\fontsize{20}{24}\bfseries\selectfont}} % \setkomafont{title}{\fontsize{20}{24}\bfseries\selectfont} \addtokomafont{title}{\fontspec{Roboto}} % \setkomafont{title}{\fontspec{Roboto}\fontsize{20}{24}\bfseries\selectfont} \addtokomafont{title}{\bfseries} % This one got rid of the font and made it bold instead XDDDDDDDDDDD I also went in Windows Shell to look at the luaotfload-tool package and force it to update after looking through the fontspec manual. I did not find anything being discussed in the KOMA-script manual or the The Not So Short Introduction to LaTeX, but I didn't do a thorough search.

I have been looking at Sockets recently, and have some questions on their behaviour. I have had a look at Practical guidelines for using sockets and Example of using plugs and sockets, as well as ltsockets-doc, and I have played with sockets in a document (mostly for testing). I would like to know if the behaviour I am seeing is expected (and will continue to work), or if it is a factor of how it is (currently) implemented, and I shouldn't rely on it. \documentclass{article} \NewSocket{enkorvaks/format-i}{1} \NewSocket{enkorvaks/format-ii}{1} \NewSocketPlug{enkorvaks/format-i}{formatibold}{Format 1: \textbf{#1}} \NewSocketPlug{enkorvaks/format-ii}{formatiitt}{Format 2: \texttt{#1}} \AssignSocketPlug{enkorvaks/format-i}{formatibold} \AssignSocketPlug{enkorvaks/format-ii}{formatiitt} \ExplSyntaxOn \tl_new:N \l_enkorvaks_formatchoice_tl \tl_set:Nn \l_enkorvaks_formatchoice_tl {format-i} \NewDocumentCommand{\sockettesting}{m}{ \UseSocket{enkorvaks/\l_enkorvaks_formatchoice_tl}{#1} } \NewDocumentCommand{\formatbold}{}{ \tl_set:Nn \l_enkorvaks_formatchoice_tl {format-i} } \NewDocumentCommand{\formattt}{}{ \tl_set:Nn \l_enkorvaks_formatchoice_tl {format-ii} } \ExplSyntaxOff \begin{document} Socket Test: \sockettesting{This should be bold (format 1)} \formattt{} Socket Test: \sockettesting{This should be tt (format 2)} \formatbold{} Socket Test: \sockettesting{This should be bold (format 1) again} \end{document} (yes, this is a trivial use, and doesn't need sockets, but this is an example only) In short, the question is: Can I use token lists (or \newcommands, I guess) as part of the \UseSocket and expect it to work into the future?

According to the https://wiki.contextgarden.net/Command/setupsidebar, sidebar works just excellent. Is there a possibility to make the different thickness of the ends of the one sidebar? For example the one is 3pt, and the other is 1pt.

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!

If I replace the inner tabularx by tabular (dropping \linewidth and changing X) it works. I would even like to use without minipage, but that it does not work with minipage, it means that minipage encapsulation is not very strict. I will have a look I think I remember an example where nested tabularx worked.

I need to draw a pulley system as in the figure. How can I do that? Specific information about the figure: A block of mass Mo is on a horizontal surface and attached by a string to a hanging block, also of mass Mo , as shown in the figure. Friction between the block and the horizontal surface is negligible. The masses of the string and pulley are negligible, and the pulley can rotate with negligible friction around its axle.
