Partial actions and proper extensions of two-sided restriction semigroups

Abstract:

 We introduce and study several classes of partial actions of two-sided restriction semigroups that generalize partial actions of monoids and of inverse semigroups. We prove a structure result on proper extensions of two-sided restriction semigroups in terms of partial actions, generalizing respective results for monoids and for inverse semigroups and upgrading the latter.


This is a joint work with Mykola Khrypchenko and Ganna Kudryavtseva
