An involution on derangements preserving excedances and right-to-left minima
arXiv:2105.08455
Abstract
We give a bijective proof of a result by R.~Mantaci and F.~Rakotondrajao from 2003, regarding even and odd derangement with a fixed number of excedances. We refine this result by also considering the set of right-to-left minima.
