Alexandroff topologies and monoid actions
Forum Mathematicum, 2020Given a monoid S acting (on the left) on a set X, all the subsets of X which are invariant with respect to such an action constitute the family of the closed subsets of an Alexandroff topology on X.

Semigroup Forum, 2002
The authors introduce and investigate a new class of monoids, called finitary monoids (here monoid means a commutative, cancellative semigroup with identity element). A monoid \(H\) (written multiplicatively) with group of invertible elements \(H^\times\) is called finitary if there is a finite subset \(U\subset H- H^\times\) such that \((H-H^\times)^n\
