On the monoid of partial isometries of a wheel graph
Vítor H. Fernandes
In this paper, we consider the monoid of all partial isometries of a wheel graph with vertices. Our main objective is to determine the rank of . In the p…
Presentations for three remarkable submonoids of the dihedral inverse monoid on a finite set
Ilinka Dimitrova, Vítor H. Fernandes, Jörg Koppitz +1
In this paper we consider the submonoids , and of the dihedral inverse monoid of all orientation-preserving,…
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…
