Endomorphism semigroups - Open Access .click

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 \(A_4\) (

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 \({\mathbf S}_n\)
