SEMILATTICE OF BISIMPLE INVERSE SEMIGROUPS

The Quarterly Journal of Mathematics, 1971
The purpose of this paper is to give a structure for a semigroup which is a semilattice of bisimple inverse semigroups and satisfies certain conditions. For such a semigroup, we characterize the idempotent separating congruences.

Ordered Left Almost ⋇-Semihypergroups Based on Fuzzy Sets

Journal of Mathematics
The concept of an involution or anti-involution is a self-inverse linear mapping that plays a prominent role in the theory of algebraic structures, particularly rings, hyperrings, ordered semigroups, and ordered semihypergroups.

A Note On Amalgams Of Inverse Semigroups

, 1999
. This note gives a necessary condition, in terms of graded actions, for an inverse semigroup to be a full amalgam. Under a mild additional hypothesis, the condition becomes sucient.

Quasi-Mixing C₀-Semigroups and Their Relations With Recurrent C₀-Semigroups

مجلة بغداد للعلوم
This article presents and investigates the concept of the quasi-mixing C0-semigroups. It is proved that the quasi-mixing of an invertible C0-semigroup is equivalent to the quasi-mixing of its inverse.

Membership and Conjugacy in Inverse Semigroups [PDF]

The membership problem for an algebraic structure asks whether a given element is contained in some substructure, which is usually given by generators.

Free Objects in Certain Varieties of Inverse Semigroups

, 1990
In this paper it is shown how the graphical methods developed by Stephen for analyzing inverse semigroup presentations may be used to study varieties of inverse semigroups.
