Presentations for monoids of endomorphisms of a star graph

Year: 2025

Type: article

Abstract: 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 finite number of vertices. Our main objective is to exhibit a presentation for each of them.
