This is U+25AD (▭) and available as \hrectangle in unicode-math (if using xelatex or lualatex) or stix if using pdflatex (and will be available in other font packages that cover the Unicode math blocks) \documentclass{article} \usepackage{stix} \begin{document} $a \hrectangle b$ \end{document}

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

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

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.

The character ⋸ is the Unicode character U+2278, see Barbara Beeton's comment. I found two math fonts, which contains the charactes: Asana Math XITS Math They can be used with XeTeX or LuaTeX. With package unicode-math, the command is \isinvb, or the character can be given directly as UTF-8 character or the ^^^^-escape notation can be used: ...

A good occasion for \ooalign, one of the best tricks in my toolbox: \documentclass{article} \usepackage{amssymb} \newcommand{\rectangle}{{% \ooalign{$\sqsubset\mkern3mu$\cr$\mkern3mu\sqsupset$\cr}% }} \begin{document} $S(\rectangle)$ \end{document} Experiment changing 3mu for different ratios between width and height.

The \downarrow symbol is an extensible delimiter: \documentclass{article} \newcommand{\xdownarrow}[1]{% {\left\downarrow\vbox to #1{}\right.\kern-\nulldelimiterspace} } \begin{document} $\downarrow \big\downarrow \Big\downarrow \bigg\downarrow \Bigg\downarrow \xdownarrow{2cm}$ \end{document}

The symbol you need to use is produced by the following command: \divideontimes

Those symbols are in IPA: \documentclass{article} \usepackage{tipa} \begin{document} \textsubbridge{t}\quad \textyogh\quad \textesh\quad \textdyoghlig\quad \textteshlig \end{document} For the last one you might prefer \texttoptiebar{t\textesh} The characters are available in some OpenType fonts, for example FreeSerif. Compile the following with ...

This is a first approximation: \documentclass{article} \newcommand{\ineq}{% \mathrel{\mkern1mu\underline{\mkern-1mu\in\mkern-1mu}\mkern1mu}} \begin{document} $\alpha\ineq\beta$ \end{document} This automatically changes size in subscripts. You may prefer a solution with a roundcap bar below the main symbol: \documentclass{article} ...

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.

You can use \renewcommand*\div{\mathbin{\mskip1mu\nonscript\mskip-1mu% ∕% \mskip1mu\nonscript\mskip-1mu}} or some value other than 1mu the skip is always added but in non-script (ie text and display) styles add the negative amount to cancel it out.

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 ...

The different 'sizes' for fonts in math-mode are: \displaystyle \textstyle \scriptstyle \scriptscriptstyle If you want to change their value, you could do: \DeclareMathSizes{d-size}{t-size}{s-size}{ss-size} In your example, I would just define a new command for your subscript: % arara: pdflatex \documentclass{article} ...

Here are some possibilities with the use of unicode (just as a demonstrative addition to Adam's answer). The Unicode for this symbol is U+22C7. % arara: lualatex \documentclass{article} \usepackage{fontspec} \usepackage{unicode-math} \begin{document} ...
