Semigroup theory examines algebraic structures consisting of a set endowed with an associative binary operation. These structures encompass a wide range of mathematical entities including monoids, ...

Monoid varieties and semigroup theory form a vibrant subfield of algebra that studies classes of algebraic structures defined by equational identities. Monoids, which are semigroups with an identity ...
