Automorphisms of endomorphism semigroups of reflexive digraphs

Mathematische Nachrichten, 2010
AbstractA reflexive digraph is a pair (X, ρ), where X is an arbitrary set and ρ is a reflexive binary relation on X. Let End (X, ρ) be the semigroup of endomorphisms of (X, ρ). We determine the group of automorphisms of End (X, ρ) for: digraphs containing an edge not contained in a cycle, digraphs consisting of arbitrary unions of cycles such that ...

Groups of order 24 and their endomorphism semigroups

Journal of Mathematical Sciences, 2007
The author proves the following result. Theorem: Let \(G^*\) be a group whose endomorphism semigroup is isomorphic to the endomorphism semigroup of a certain group \(G\) of order 24. Then 1) if \(G=\langle a,b\mid b^3=1\), \(aba=bab\rangle\) (the binary tetrahedral group), then \(G^*\cong G\), or the group is isomorphic to the indefinite group \(A_4\) (

On the endomorphism monoids of Clifford semigroups

Asian-European Journal of Mathematics, 2018
In this paper, we study properties of the endomorphism monoids of strong semilattices of groups. In Sec. 2, several properties for endomorphism monoids of finite semilattices are investigated. In Sec. 3, we collect some results on endomorphism monoids of strong semilattices of groups, i.e. Clifford semigroups.

Topology of the Semigroup of Singular Endomorphisms

SemiGroup Forum, 2000
\(\text{End}(V)\) is the semigroup of all endomorphisms of an \(n\)-dimensional vector space \(V\) over either the field \(\mathbb{R}\) of real numbers or the field \(\mathbb{C}\) of complex numbers. The subsemigroup of \(\text{End}(V)\) consisting of all singular endomorphisms is denoted by \({\mathbf S}_n\) and it is well known that \({\mathbf S}_n\)
