Adian Inverse Semigroups

, 2016
The class of Adian semigroups and Adian groups was first introduced and studied by S. I. Adian in 1966. We introduce the notion of Adian inverse semigroups with the hope that the study of these objects may help in resolving some of the remaining open ...

A class of varieties of inverse semigroups

, 1991
Let Wr(U, V) denote the variety of inverse semigroups generated by wreath products of semigroups in U with semigroups in V, where U and V are varieties of inverse semigroups.

A New Approach to the Study of the Existence and Uniqueness of Mild Solutions for an Evolving System by Using Fractional Derivatives in the Deformable Sense

International Journal of Mathematics and Mathematical Sciences
In this work, we study the existence and uniqueness of mild solutions for linear and semilinear control systems using the new deformable fractional derivative.

Idempotent pure extensions by inverse semigroups via quivers

, 1998
In this paper we describe idempotent pure regular extensions by inverse semigroups by means of quivers and actions of inverse semigroups, generalising the category and action of groups approach presented by Margolis and Pin for E-unitary inverse ...

Monogenic free inverse semigroups and partial automorphisms of regular rooted trees

Математичні Студії
For a one-to-one partial mapping on an infinite set, we present a criterion in terms of its cycle-chain decomposition that the inverse subsemigroup generated by this mapping is monogenic free inverse. We also give a sufficient condition for a regular

INVERSE SEMIGROUPS OF PARTIAL AUTOMATON PERMUTATIONS

, 2010
The inverse semigroup of partial automaton permutations over a finite alphabet is characterized in terms of wreath products. The permutation conjugacy relation in this semigroup and the Green's relations are described.

HNN extensions of inverse semigroups

, 1997
The concept of HNN-extensions of groups was introduced by Higman, Neumann and Neumann in their study of embeddability of groups in 1949. In combinatorial group theory, HNN-extensions play an important role in applications to algorithmic problems.
