While it would be possible to get the arrow you want, it's better to use a dedicated package for drawing these diagrams: \documentclass{article} \usepackage{amssymb} \usepackage{tikz-cd} \begin{document} \begin{tikzcd}[column sep=1.2em] 0 \arrow[r] & C_{3} \arrow[r,hook] & \mathit{SL}_{3}(\mathbb{C}) \arrow[r,two heads] & ...

May be this: \documentclass{article} \newcommand\mysym{% \mathrel{% {% \ooalign{\hidewidth$\mkern3mu\circ$\hidewidth\cr$<$}% }% }} \begin{document} $x\mysym U$ \end{document}

I would recommend the unicodes U+2A79 and U+2A7A for this, as they are already defined in unicode-math. They are less similar to \sphericalangle and thus easier to distinguish. You need Lua- or XeLaTeX for this. % arara: lualatex \documentclass{article} \usepackage{unicode-math} \usepackage{fontspec} \begin{document} \setmathfont{XITS Math} ...

Inventing new binary relations is hard on the typesetting :) I can suggest combining it by hand, like the following \newcommand{\lcirc}{<\hspace{-8pt}\circ} $\lcirc$ On the first glance I don't find an existing similar symbol in http://mirrors.ctan.org/info/symbols/comprehensive/symbols-a4.pdf

This link shows a way of using \smashoperator[r] in mathtools. \begin{align*} \begin{array}{c} \min \: A = \min \: \smashoperator[r]{\sum_{i\in B}} C_i \\ \\ \min \: D = \min \: \smashoperator[r]{\sum_{i\in B}} \pi_i \cdot F_i \end{array} \end{align*}

EPS was designed to import postscript code, which did not include fonts. The necessary fonts had to either be installed on the output device or downloaded with the job. PDF was created to allow pages to stand alone, including embedding fonts. So, when using EPS in publishing, standard practice was to convert any type to outlines when saving (say from ...

I would follow egreg's comment, all italic, or all upright. In case it's a special occasion, then don't redefine \pi but define another command. \documentclass{scrartcl} \usepackage{mathtools} \usepackage{unicode-math} \setmainfont{Minion Pro} \setmonofont{Consolas}[Scale=MatchLowercase] \setmathfont[Scale=MatchLowercase]{TGPagellaMath} ...

Well, Private Use Areas are part of Unicode, they just have no predefined meaning. So you can use them like any other character, e.g. by simply typing it (if you have an appropriate input method) or using the character code either as \char"F3A0F or ^^^^^f3a0f. If I run your example here, I get a PDF with the symbol both with LuaTeX and XeTeX.

Possibly the pic syntax provides one fairly easy way to go: \documentclass[varwidth, border=5]{standalone} \usepackage{tikz} \tikzset{symbols/.cd, smiley/.pic={ \draw circle [radius=1/2] (225:1/3) arc (225:315:1/3) (135:1/4) circle [radius=1/32] (45:1/4) circle [radius=1/32]; } } \newcommand\tikzsymbol[2][]{\tikz\pic[#1]{symbols/#2};} ...

If you want really curly curly braces and wish to use a Times-like math font -- as would seem to be the case because of your consideration of the newtxmath package -- you should look into using the mtpro2 font package. ("mtpro2" is short for "MathTime Professional II".) The full mtpro2 package isn't free of charge. However, its "lite" subset, which is all ...

○ as is used for (f ○ g)(x) is Alt+9. I just posted this so if someone needed it, it was here.

The glyphs are not supported by Libertine in TS1 encoding. Why? I don't know. However in the log file you find Missing character: There is no <B4> in font LinLibertineT-tlf-ts1! Missing character: There is no <80> in font LinLibertineT-tlf-ts1! Missing character: There is no <80> in font LinLibertineT-tlf-ts1! Missing character: There is ...

I do not know a package which defines the most common currency signs. I would just search a font which has them all. You may want to search the unicode of the existing symbols first: http://www.fileformat.info/info/unicode/category/Sc/list.htm Here is the Turkish symbol with use of its unicode (and siunitx): % arara: lualatex \documentclass{article} ...

The musixtex package provides a font (in five sizes and only one variant) which has the symbol (instead of a »3«). Here is one possibility to use it in text: \documentclass{article} \DeclareFontFamily{U}{musix}{}% \DeclareFontShape{U}{musix}{m}{n}{% <-12> musix11 <12-15> musix13 <15-18> musix16 <18-23> musix20 <23-> ...

There is a unicode for this and here are the four fonts I could find to set this: % arara: lualatex \documentclass{article} \usepackage{fontspec} \begin{document} A{\fontspec{code2001_0.ttf}\symbol{"1D12B}}B{\fontspec{freeserif.ttf}\symbol{"1D12B}}D{\fontspec{quivira.otf}\symbol{"1D12B}}E{\fontspec{symbola.ttf}\symbol{"1D12B}} \end{document} ...

Some more free available versions: % arara: lualatex \documentclass{article} \usepackage{fontspec} \begin{document} Script Capital H: {\fontspec{arialuni.ttf}\symbol{"210B}} {\fontspec{code2000.ttf}\symbol{"210B}} {\fontspec{dejavusans.ttf}\symbol{"210B}} {\fontspec{freeserif.otf}\symbol{"210B}} ...

You can get something very similar to what Mico showed using \mathscr{H} and mathrsfs, which is free. \documentclass{standalone} \usepackage{mathrsfs} \begin{document} $\mathscr{H}$ \end{document}

2

The H produced by the \mathscr macro of the MathTime Pro 2 Professional font package -- note that it's not free of charge -- may (or may not...) be what you're looking for: \documentclass{article} \usepackage[mtpscr]{mtpro2} % http://www.pctex.com/mtpro2.html \begin{document} $\mathscr{H}$ \end{document} Many more possibilities present themselves if ...

You could think of ${\overline A}_1$ as being defined as $\overline{A_1}$ in which case you have the shorter line and can just write \overline A_1.

1

Certainly something like $\overline{A_1}$, because it is closure of $A_1$. But I understand, that the rule may look a bit too long for you. Indeed, there is no italic correction for math font. If you prefer a bit shorter version, see, e.g. answers to Appearance issues with \bar{} and \underline{}.

Here are some possibilities: \documentclass{article} \begin{document} $x^{*2}\quad x^{*\,2}\quad {x^{*}}^{2}\quad (x^{*})^{2}$ \end{document} I'd prefer the last one that's less ambiguous.

I thought this question has come up before, but maybe not. How about something like $\overline{\kern-2pt\int}\underline{\kern2pt{\!\int\!}}$ $\overline{\!\int}\underline{\>{\!\int\!}}$ \bye Or this one \eqalign{\bar{\kern-2pt{\!\!\int\!{}}}\quad\underline{\kern-2pt{\int\!\!\!}}} \bye

How about using cmbright to get sans serif math and rotating the \partial? \documentclass{article} \usepackage{cmbright} \usepackage{graphicx} \newcommand{\upartial}{\rotatebox[origin=c]{15}{\ensuremath{\partial\mkern-2mu}}} \begin{document} $\frac{\partial x}{\partial t}\quad\textnormal{vs.}\quad\frac{\upartial x}{\upartial t}$ \end{document} Edit: ...

Partial solution. \usepackage{graphicx} \renewcommand*\partial{\textsf{\reflectbox{6}}}

It seems that there are appearing bugs in unicode-math. Here's a workaround: load the prime from a math font after loading the fonts. By the way, it's necessary to call \setmathfont with the original font after any others to set the correct “fontdimens”. \documentclass{scrartcl} \usepackage{unicode-math,polyglossia} \setmainfont{Gentium} ...

You can get automatically the § symbol (which I don't recommend, though) with cleveref and its \cref command. It's better to have a different command than \ref, because you might need the latter for referring the section without the § prefix. The § symbol is obtained with \S. \documentclass{article} %\usepackage{hyperref} % not needed; should go before ...

1

It may be best to define a new command, say \secref that you use for references to sectional units, while using \ref for everything else: \newcommand{\secref}[1]{\S\ref{#1}} hyperref provides this functionality via its \autoref feature. You merely have to define the \<counter>autorefname macros accordingly: \documentclass{article} ...

I used the detexify website to search the sign you are asking. %pdflatex \documentclass[margin=0.5mm]{standalone} \usepackage{textcomp} \begin{document} \textsection \end{document} The usage is simple, just assign a reference tag to the chapter you want, and then add that reference tag besides to this sign in your text. Please read the following page: ...
