Presentations for monoids of endomorphisms of a star graph
Vitor H. Fernandes, Jörg Koppitz, Tiwadee Musunthia
In this paper, we consider the monoids of all endomorphisms, of all weak endomorphisms, of all strong endomorphisms and of all strong weak endomorphisms of a star graph with a fini…
Presentations for monoids of partial endomorphisms of a star graph
Ilinka Dimitrova, Vítor H. Fernandes, Jörg Koppitz
In this paper, we consider the monoids of all partial endomorphisms, of all partial weak endomorphisms, of all injective partial endomorphisms, of all partial strong endomorphisms…
On partial endomorphisms of a star graph
Ilinka Dimitrova, Vítor H. Fernandes, Jörg Koppitz
In this paper we consider the monoids of all partial endomorphisms, of all partial weak endomorphisms, of all injective partial endomorphisms, of all partial strong endomorphisms a…
On monoids of endomorphisms of a cycle graph
Ilinka Dimitrova, Vítor H. Fernandes, Jörg Koppitz +1
In this paper we consider endomorphisms of an undirected cycle graph from Semigroup Theory perspective. Our main aim is to present a process to determine sets of generators with mi…

Ilinka Dimitrova, Vítor H. Fernandes, Jörg Koppitz +1
In this paper we consider three submonoids of the dihedral inverse monoid , namely its submonoids , and of all…
