I'd like to be able to use a wavy arrow, one that is a bit rounder and has a slower oscillation than rightsquigarrow: ideally one that has the exact same wave as a tilde, and ends in an arrowhead, and use it in equations in the same way as a \sim b.

Is there an easy way to do this?

Edit: leadsto from murray's answer is very close. To be even more precise - is there a way to adjoin an arrowhead to a tilde? I'll have a look at Steven's suggestions later today.

Using Detexify (http://detexify.kirelabs.org/classify.html), one finds the amssymb symbol \leadsto. Perhaps that's what you want.

\documentclass{article}
\usepackage{amsmath,amssymb}

\newcommand{\curly}{\mathrel{\leadsto}}


\begin{document}


$a \curly b$


\end{document}

\leadsto as math relation

(Comment: Is \leadsto already a math relation? I'm not sure yet.)

Another possibility is \leadsto from latexsymb.

  • (I think thats the rightsquigarrow picture you posted.) Excellent link, thank you! \leadsto is very close to a tilde indeed, hence almost perfect :) – user8463 Oct 06 '20 at 16:33
  • Actually, package amssymb defines \leadsto to be the zigzag arrow with sharp angles that is also called \rightsquigarrow (other packages, such as mathdesign with the option utopia, do the same with their own version of the glyph), whereas package latexsym defines \leadsto to be the smoothly-waving arrow. This is annoying. – Maëlan May 24 '22 at 21:53
