Ranks and presentations of some normally ordered inverse semigroups
Rita Caneco, Vítor H. Fernandes, Teresa M. Quinteiro
In this paper we compute the rank and exhibit a presentation for the monoids of all -stable and -order preserving partial permutations on a finite set , with an ordere…

Presentations for monoids of finite partial isometries
Vítor H. Fernandes, Teresa M. Quinteiro
In this paper we give presentations for the monoid of all partial isometries on and for its submonoid of all order-preserving pa…
