Ranks and presentations of some normally ordered inverse semigroups

Research output: Contribution to journalArticlepeer-review

Abstract

In this paper we compute the rank and exhibit a presentation for the monoids of all P-stable and P-order preserving partial permutations on a finite set Ω , with P an ordered uniform partition of Ω. These (inverse) semigroups constitute a natural class of generators of the pseudovariety of inverse semigroups NO of all normally ordered (finite) inverse semigroups.
