The rank of the semigroup of order-, fence-, and parity-preserving partial injections on a finite set

Apatsara Sareeto, Jörg Koppitz

The monoid of all partial injections on a finite set (the symmetric inverse semigroup) is of particular interest because of the well-known Wagner-Preston Theorem. In this article,…
