math-modesymbols
Suppose I have a map A → B which is an isomorphism. I'd like to represent this as something that looks like \rightarrow with \simunder it. I could try \underset{}_{}, but is there already a ready made symbol?
I couldn't find the symbol using Detexify, nor in the comprehensive list of LaTeX symbols.
\udtimes is defined in the mathdesign package
Probably quick and dirty, see ISO character entities and their LaTeX equivalents on page 3:
${^c\!/\!_o}$ Jim Jones
Edit: Included suggestion from Tobi’s comment having the letters c and o non-italicised:
$\mathrm{^c\!/\!_o}$ Jim Jones

Theoretically, you could use
\xrightarrow[\sim]{}(fromamsmath) or\xlongrightarrow[\sim]{}(fromextarrows). Both look horrible though. The\simon top of the arrow (like\xlongrightarrow{\sim}) looks somewhat better.Unicode defines ⥴ (U+2974 RIGHTWARDS ARROW ABOVE TILDE OPERATOR), which you can use in case you run Xe/LuaLaTeX with
unicode-math(either directly or with the\rightarrowsimilaralias). There are also ⥱ (\equalrightarrow), ⥲ (\similarrightarrow), ⥳ (\leftarrowsimilar), ⥵ (\rightarrowapprox) and other strange things.
