In mathematics, an involution is a function that is it’s own inverse. Involutions are sometimes also called involutory functions. So, for an involutory function f:
![\[f(f(x)) = x\]](https://neuraldump.net/wp-content/ql-cache/quicklatex.com-d7bb5ba6176102f4c590b41d5486f4d5_l3.png "Rendered by QuickLaTeX.com")
for all x in the domain of f.
