Homomorphisms of wn-right cancellative, wn-bisimple, and wnI-bisimple semigroups
, 1969 R. J. Warne has defined an wn-right cancellative semigroup to be a right cancellative semigroup with identity whose ideal structure is order isomorphic to (Io)n, where Io is the set of non-negative integers and n is a natural number, under the reverse ...

The conjugacy relation plays an important role in group theory. If $a$ and $b$ are elements of a group~$G$, $a$ is conjugate to $b$ if $g^{-1}ag=b$ for some $g\in G$.

GROWTHS OF ENDOMORPHISMS OF FINITELY GENERATED SEMIGROUPS [PDF]
Journal of the Australian Mathematical Society, 2016 This paper studies the growths of endomorphisms of finitely generated semigroups. The growth is a certain dynamical characteristic describing how iterations of the endomorphism ‘stretch’ balls in the Cayley graph of the semigroup. We make a detailed study of the relation of the growth of an endomorphism of a finitely generated semigroup and the growth ...

A Note on Endomorphism Semigroups
Canadian Mathematical Bulletin, 1970 If is a universal algebra, the set of endomorphisms of forms a monoid (i.e., semigroup with identity) under composition. We denote it by End (). For definitions and notations, see [1]. It is well known (e.g., [1], Theorem 12.3) that for any monoid M there is a unary algebra with M ≅ End (). E. Mendelsohn and Z.

Automorphisms of endomorphism semigroups of reflexive digraphs
Mathematische Nachrichten, 2010AbstractA 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 ...
