On the cyclic inverse monoid on a finite set
Vitor Hugo Fernandes
In this paper we study the cyclic inverse monoid $\CI_n$ on a set with elements, i.e. the inverse submonoid of the symmetric inverse monoid on consisting of all res…
Endomorphisms of semigroups of oriented transformations
De Biao Li, Vítor H. Fernandes
In this paper, we characterize the monoid of endomorphisms of the semigroup of all oriented full transformations of a finite chain, as well as the monoid of endomorphisms of the se…
On the monoid of partial isometries of a cycle graph
Vítor H. Fernandes, Tânia Paulista
In this paper we consider the monoid $\DPC_n$ of all partial isometries of a -cycle graph . We show that $\DPC_n$ is the submonoid of the monoid of all oriented partial per…
On the monoid of partial isometries of a finite star graph
Vítor Hugo Fernandes, Tânia Paulista
In this paper we consider the monoid of all partial isometries of a star graph with vertices. Our main objectives are to determine the rank and to exhibit a prese…
