Question

In my current work I need to use arrow symbols, representing injection, surjection and bijection. First two can be given by commands \rightarrowtail and \twoheadrightarrow, but the bijection arrow – Unicode 2916 character – is not present in the list of LaTeX arrow characters. How can I add the mentioned symbol in my text ? Maybe some additional packages should be used ?

I’m new to LaTeX, so any help will be appreciated.
Thanks in advance.

Answer 1

I can emulate it like this :

\documentclass{minimal}

\usepackage{amssymb}

\begin{document}

$\rightarrowtail\!\!\!\!\!\rightarrow $

\end{document}

I would also advise looking at the Comprehensive LaTeX symbol List in general.
