We consider the relationship between the combinatorial properties of semigroupoids in
general and semigroups in particular. We show that a semigroupoid is finitely generated …

In this thesis we consider in detail the following two problems for semigroups:(i) When are
semigroups finitely generated and presented?(ii) Which families of semigroups can be …

In this thesis we consider in detail the following two fundamental problems for semigroup
presentations: 1. Given a semigroup find a presentation defining it. 2. Given a presentation …

In this paper we consider finite generation and finite presentability of Rees matrix
semigroups (with or without zero) over arbitrary semigroups. The main result states that a …

A finite semigroup S is said to preserve finite generation (resp., presentability) in direct
products, provided that, for every infinite semigroup T, the direct product S× T is finitely …

The beginnings of combinatorial semigroup theory date from the middle of last century,
motivated by the study of combinatorial group theory. Nevertheless, it was only in recent …

We study properties determined by idempotents in the following families of matrix
semigroups over a semiring S: the full matrix semigroup M n (S), the semigroup UT n (S) …
