In what font is this curly T from Lee's Introduction to Topological Manifolds? Closest I could find was from TeX font eusm10:

I want two edges in this figure here that are bent and join v_2 with v_5 and v_2 with v_11 but remain in the big ellipse. The usual bend command does not allow me to do that, I have also tried some AI to help. I know there are some sophisticated answers about similar issues but I would like something simple that fixes this problem here easily. \begin{tikzpicture}[semithick, line cap=round, line join=round, scale=0.8] % --- Parameters --- \def\r{0.2} % Small circle radius % --- Coordinates --- \coordinate (ET) at (0, 3); % v1 \coordinate (EB) at (0, -3); % v2 % Inner Circles Points \coordinate (C1T) at (-3, \r); % v5 \coordinate (C1B) at (-3, -\r); % v6 \coordinate (C2T) at (-1, \r); % v7 \coordinate (C2B) at (-1, -\r); % v8 \coordinate (C3T) at (1, \r); % v9 \coordinate (C3B) at (1, -\r); % v10 \coordinate (C4T) at (3, \r); % v11 \coordinate (C4B) at (3, -\r); % v12 % --- Drawing Boundaries (Solid) --- \draw[thick] (0,0) ellipse (5 and 3); \foreach \x in {-3,-1,1,3} { \draw[thick] (\x,0) circle (\r); } % --- Inner Edges (Dashed) --- % 1.

None of the solutions here work for me. Google says to use acroviewR15 but Adobe says to use acroview. acroviewR25 doesn't work either.

Here is a MWE which uses 'pdflatex' and is compiled in TeXstudio with texlive2024. \documentclass{article} \usepackage{natbib} \bibliographystyle{plain} \newcommand{\hcite}[1]{{\setcitestyle{square,super}\cite{#1}}} \begin{document} The existing command ``\verb|\cite{he2016deep}|'' leads to ``refer to \cite{he2016deep}''. \\ My command ``\verb|\hcite{he2016deep}|'' leads to ``refer to the paper\hcite{he2016deep}''. \bibliography{ref.bib} \end{document} '\cite' has a completion word list (cwl) like the following. However, my command '\hcite' does not have that cwl. Hence I want to know how to make this command also have a completion word list in TeXstudio? Thanks in advance!

When I turn on headings for entries in index, I get the following error: ! LaTeX Error: Invalid UTF-8 byte sequence (�\check@icr).

I want to have subsections after each section to be numbered starting at 0: Section 1.0 Subsection 1.1 Subsection 1.2 Subsection Section 2.0 Subsection 2.1 Subsection 2.2 Subsection I know I can achieve with the command \setcounter{subsection}{-1} after each \section{} command (Getting section numbering to start at 0), but I do not want to do it manually everytime. I have been suggested both \usepackage{etoolbox} \apptocmd{\section}{\setcounter{subsection}{-1}}{}{} and \AddToHook{cmd/section/after}{\setcounter{subsection}{-1}} but none works for me. I have no problem using a package like etoolbox, but I prefer solutions that do not depend on packages if possible.

I have answer blanks on an exam, and then I like to fill them in with the answers. Because the answer may need to be a displayed equation, I put it all in a parbox that gets underlined. This all works fine, until I try to enable tagging, at which point the displayed equation causes "Package tagpdf Error: The number of automatic begin and end text para hooks differ!" Is there a tagging friendly way to underline a parbox? \DocumentMetadata{lang=en-US,tagging=on} \documentclass{article} \begin{document} 1. \underline{\parbox{1in}{~}}\par 2. \underline{\parbox{1in}{\makebox[1in]{}}}\par 3. \underline{\parbox{1in}{okay}}\par 4. \underline{\parbox{1in}{$okay$}}\par 5. \underline{\parbox{1in}{\[not~okay\]}} \end{document}

Consider the following piece of code (MWE): \documentclass{article} \usepackage{siunitx} \usepackage{mathtools} \newcounter{A} \setcounter{A}{1} \begin{document} $\begin{array}{c} \text{\arabic{A}:} \text{\arabic{A}\stepcounter{A}:} \text{\arabic{A}\stepcounter{A}:} \text{\arabic{A}\stepcounter{A}:} \text{\arabic{A}\stepcounter{A}:} \end{array}$ \end{document} Compiling with the 2025 TeX distribution, it produces the following output: 1:2:6:10:14 which is very unexpected, since I just increment the counter A once by line. On the other hand: Compiling with the 2024 or 2023 TeX distribution yields the expected output 1:2:3:4:5 The expected output is also obtained if we swap the two line \usepackage{siunitx} and \usepackage{mathtools}. Can anyone explain this strange behavior to me?

I employ BibTeX to create formatted bibliographies. When one uses numeric-style citation call-outs (say, with the help of the plain or abbrv bibliography style), the citation call-outs are shown as arabic numerals by default. Question: Is there a way to employ uppercase Latin-alphabet letters -- A to Z -- instead of arabic numerals?

Built in math operators like \sin and \cos have the property that if a delimiter (such as a parenthesis, bracket, or brace) is placed after, there is no space between the operator and the delimiter. For example, \sin(x) and \sin (x) are both rendered without a space in the middle. On the other hand, if there is no delimiter after, there is always a space before the next character. For example, \sin\alpha and \sin x are both rendered with a space in the middle. My question is how do I define math operators that have this property? For example, I would like to define the principal argument of a complex number as "Arg" with the capital "A."

Allagedly, command \mupdelta in math mode should give an upright lowercase Greek delta, as shown in this table from unimath-symbols: However, with lua-unicode-math, the result of \mupdelta is not upright, as shown in the first letter of the output below.

I got a question regarding the enumerate-environment whilst I was looking at the TeX-errorlog by Donald E. Knuth himself. I tried to find a solution online (Google) but was not successful. It splits up in three: How is it possible to Put a text on the left hand side next to the enumeration-label like he is always doing it. E.g. 12 $\mapsto$ \textbf{13} on page 1 of his log. Put a text on the right hand side of the entire line, like §240 D on page 1 of his log. Have a header in the middle of the line without breaking the enumeration. The error-log can for example be found here: https://ctan.math.washington.edu/tex-archive/info/knuth-pdf/errata/errorlog.pdf. My ideas for the specific questions: use \item[$12 \; \mapsto$ \textbf{13}] and set the enumerate-item counter manually which is a suboptimal way. use the flushright environment (or perhaps \hfill?) which is also suboptimal, if the text within the enumeration item is multiple lines and I only want the text to appear on the first line. using the pause-feature of enumerations, breaking the enumeration with \end and starting it again. I cant imagine that this is the way Knuth was doing it. There has to be a way to achieve this more elegantly. Thanks.

Currently we use pdflatex and have to look like word a bit. Means we use fonts helvet for base text, mathptmx for math and courier for code samples. Well, now we want to switch to fonts offered by texlive for sake of reproducibility and if possible avoid proprietary ones. I found already tgheros a good substitute for helve, isn't it? For the rest, no idea, I heared luximo for courier... What worries me more is, that we will switch to lualatex in future and for this I could not find reasonable substitutes. I tried \setmainfont{TeXGhreHeros}[several trials] but nothing is really close to helvet. For the other fonts also no clue. What are your suggestions? Is the problem I describe a common one?

I want to create mps from mp code with mpost. My mp files always have a single pic only. On the console I use something like mpost -interaction=nonstopmode -recorder -s prologues=2 -s 'outputtemplate="%j.mps"' F4_05someMetapost which seems to work fine for both linux and windows. Now I try to write some entry in .latexmkrc doing the same. From How to use latekmk with feynmf/feynmp? I have add_cus_dep('mp', '1', 0, 'mpost'); sub mpost { my $file = $_[0]; my ($name, $path) = fileparse( $file ); pushd( $path ); my $return = system "mpost $name" ; popd(); return $return; } but I wonder how to place the quotes to get it right. If nothing helps, I drop -s 'outputtemplate="%j.mps"' and do a simple move of xxx.1 to xxx.mps. In fact, there are restrictions, we need flexibility to put in various options so better to process general options for mpost. A first step would be to setup the above invocation of mpost within my .latexmkrc file.

I understand that this is related to TeX’s expansion mechanism, but I do not know how to structure the macros so that each call preserves its own value of \varReponsePremiereLigne (or is expanded at the right time). How to fix this so that multiple calls to \reponsePremiereLigne{...} and \reponseDeuxiemeLigne{...} behave correctly? Thank you very much.

This is a long fragment of code but it is the shortest one I could get showcasing my problem, sorry for that: \documentclass[12pt,oneside]{book} \usepackage[shortlabels]{enumitem} \usepackage{multicol} \usepackage{pgfplots} \pgfplotsset{compat=newest} \usepackage{tikz} \usetikzlibrary{shapes,backgrounds,fit} \begin{document} \begin{enumerate} \item[Exercise 1] \begin{enumerate} \begin{multicols}{2} \item \phantom{O} \begin{center} \begin{tikzpicture} \begin{scope} \draw (0,0) rectangle (5,5); \end{scope} \end{tikzpicture} \end{center} \item \phantom{O} \begin{center} \begin{tikzpicture} \begin{scope} \draw (0,0) rectangle (5,5); \end{scope} \end{tikzpicture} \end{center} \end{multicols} \begin{multicols}{2} \item \phantom{O} \begin{center} \begin{tikzpicture} \begin{scope} \draw (0,0) rectangle (5,5); \end{scope} \end{tikzpicture} \end{center} \item \phantom{O} \begin{center} \begin{tikzpicture} \begin{scope} \draw (0,0) rectangle (5,5); \end{scope} \end{tikzpicture} \end{center} \end{multicols} \end{enumerate} \end{enumerate} \end{document} The result is this: What I don't understand is, why (a) is located in the upper-left corner of the picture (how I wanted it to be), while (c) is located in the bottom-left of its corresponding picture? I noticed that if I change \item[Exercise 1] to \item Exercise 1 the problem goes away, but I really wanted to know why this happens, and how could I avoid it without making this change. My question sounds similar to this one, but I don't think they are the same.

I'd like to create footnotes where a verse number (rather than a counter) is shown in the apparatus next to the note text. Also, if more than one note occurs on a page for a particular verse, instead of prefixing subsequent notes for that verse with the verse number, I'd like to just see a separator, such as the vertical bar character "|". However, if the footnotes for a particular verse are present on two separate pages, I'd like the verse number to appear again on the second page. So it becomes important in this situation to know the final page number that a footnote will end up on. In other words, if verse 34 is near the end of page 1, and it has two footnotes that appear on page 1, then the first footnote will be prefixed in the apparatus with "34", while the second footnote will be prefixed by "|". Now let's say verse 34 has a third footnote, but that note appears on the next page. I'd like that note to be prefixed by "34" again in the apparatus. So the final page number that the note falls on has an effect on what prefix appears with the note in the apparatus. Here's a minimum working example that demonstrates the problem: \startluacode userdata = userdata or {} userdata.last_verse = 0 userdata.last_chapter = 0 userdata.last_page = 0 function userdata.get_verse_label(curr_chap, curr_verse) local curr_page = tex.count["realpageno"] local label = "" if curr_page > userdata.last_page then userdata.last_verse = 0 userdata.last_page = curr_page end if curr_verse == userdata.last_verse then label = "{\\bf \\textbar\\space}" else label = "{\\bf " .. curr_verse .. "\\space}" end userdata.last_chapter = curr_chap userdata.last_verse = curr_verse context(label) end \stopluacode \newcount\CurrentVerse \newcount\CurrentChapter \unexpanded\def\setverse#1#2{% \global\CurrentChapter=#1 \global\CurrentVerse=#2 #2 } \definenote[footnote][way=bypage, location=page] \setupnotation[footnote][number=no, alternative=serried] \setupnote[footnote][ rule=yes, location=page, width=\textwidth, paragraph=yes, alternative=serried, indenting=no ] \def\note#1{% \footnote{% \ctxlua{userdata.get_verse_label(\the\CurrentChapter, \the\CurrentVerse)}% #1% } } \starttext \dorecurse{100}{ \setverse{1}{\recurselevel}This is some text with footnotes.*\note{This is a first footnote for verse \recurselevel.}\note{This is a second footnote for verse \recurselevel.} } \stoptext In this example, you can see the following output on page 2 of the PDF: If you look at the first footnote appearing on page 2, you can see the second footnote that belongs to verse 34. Since this is the first note that appears on the page for that verse, I'd like the verse number to show up. However, I think that my Lua code, when it calls tex.count["realpageno"], is only seeing a first-pass page number. When that second footnote for verse 34 gets ultimately bumped to page 2, it's already been typeset with the vertical bar. My question: Is there a way to modify my Lua to have access to the final page number for the note, and to modify the note prefix accordingly? Incidentally, the reason I'm doing this is to emulate the footnote apparatus for the Nestle-Aland editions. So this is a real world need. UPDATE: Here's another way of indicating what I'm looking for: I understand that in ConTeXt if I label a footnote like this: \footnote[fnfirst]{This is some footnote text.} Then I can elsewhere refer to the final page number for that footnote with \at{page}[fnfirst]. So the question is: Is there a way (in ConTeXt or Lua) to access the value of \at{page}[...] and use that value in logic to modify whether the footnote in the apparatus is prefixed with a verse number or with a "|" separator character?

This \documentclass[a4paper,12pt]{article} \usepackage{tcolorbox} \tcbuselibrary{most} \tcbset{skin=enhanced} \begin{document} \begin{tcolorbox}[flip title, title=hi] Some content \begin{tcolorbox}[flip title, title=hi] \end{tcolorbox} \end{tcolorbox} \end{document} leads to the outer box having a flip title, while the inner does not. I believe I have understood that this is because boxed titles are drawn as underlays. Is there some way to have them drawn as e.g. overlays instead, without having to resort to manually imitating them via TikZ?

Edit: On account of some stress while writing up the document, I wrongly stated in the comments below that the beamer was in pdf-tex. That was the major factor which created strong criticism from some, or at least so I think. The criticism should have been constructive, it seems to me, and directed towards my wrong claim that it is a pdf-tex preamble. If so, I would have resolved the problem myself by means of the benefits LuaLaTex provides. I have has this \newcommand{\Vis}{\boldsymbol{!}} for a bold and fat exclamation mark to serve as an operator. Some advised me to use \newcommand{\Avail}{\mathord{\raisebox{0.2ex}{\rotatebox{180}{$\boldsymbol{!}$}}}} for the dual operator with an upside-down exclamation mark. But the latter definition generated stability problems or something like that, in the document. Is there a more stable manner to obtain the dual operators which I want, which I may put into my preamble, which is as follows? \documentclass[english,aspectratio=169]{beamer} % ========================= % LuaLaTeX font setup % ========================= \usepackage{fontspec} % ========================= % Graphics % ========================= \usepackage{tikz} % Serif text font (safe, neutral) \setmainfont{Latin Modern Roman} % Math font %\setmathfont{Latin Modern Math} % ========================= % Language and typography % ========================= \usepackage[english]{babel} \babelprovide[import]{arabic} \babelprovide[import]{persian} \usepackage{luabidi} \babelfont[arabic]{rm}{Amiri} \babelfont[persian]{rm}{Amiri} \usepackage{microtype} \usepackage{url} % ========================= % Mathematics % ========================= \usepackage{amsmath} % Also has \boldsymbol \usepackage{mathtools} %========================== \usepackage{bm} % For \bm (often preferred to \boldsymbol %under \usepackage{amsmath} for better spacing) %========================== % ========================= % UiO Beamer theme % ========================= \makeatletter\let\arrowvert\@undefined\makeatother%To avoid expand LaTeX Error: Command `\arrowvert' already defined.‪/usr/local/texlive/2023/texmf-dist/tex/latex/newtx/newtxmath.sty, 878‬ \usefonttheme{professionalfonts} \usetheme{UiO} \urlstyle{sf} % -------------------------------------------------------- %Graphics (required for \rotatebox) %--------------------------------------------------------- \usepackage{graphicx} % ========================= % Semantic macros % ========================= \newcommand{\defeq}{\mathrel{\vcentcolon=}} \newcommand{\Vis}{\boldsymbol{!}} \newcommand{\Avail}{\mathord{\raisebox{0.2ex}{\rotatebox{180}{$\boldsymbol{!}$}}}} \newcommand{\Tr}{\mathsf{Tr}} \newcommand{\Aut}{\mathsf{AE}} % ========================== % Bend supports %=========================== \newcommand{\godel}[2][]{% \mspace{1\medmuskip}% \vphantom{#2}% \begin{tikzpicture}[baseline=(M.south)] \node[inner ysep=0pt,inner xsep=4pt](M){\smash[b]{$#2\mathstrut$}}; \draw[rounded corners=.5mm,#1]([xshift=-1mm]M.south east)--(M.south east)--++(0,.14); \draw[rounded corners=.5mm,#1]([xshift=1mm]M.south west)--(M.south west)--++(0,.14); \end{tikzpicture}% \mspace{1\medmuskip}% } % ========================= % Bibliography matters % ========================= \usepackage[ backend=biber, style=authoryear, maxbibnames=3, giveninits=true ]{biblatex} \renewbibmacro*{in:}{} \addbibresource{lassiclib.bib} % ========================= % Front matter % ========================= \begin{document} $\Avail{\godel{A}}\defeq$ just if $\vdash A\wedge \ldots$ Compare $!$ with $\Avail{~}$ \end{document}
