Normal extensions and full restricted semidirect products of inverse semigroups
Mária B. Szendrei
We characterize the normal extensions of inverse semigroups isomorphic to full restricted semidirect products, and present a Kalouznin-Krasner theorem which holds for a wider class…
A tribute to Mario Petrich
Pedro V. Silva, Mária B. Szendrei
This paper was written as a tribute to Mario Petrich, a major figure in the history of semigroup theory. Publication is posthumous in view of his recent death.
Structure theory of regular semigroups
Mária B. Szendrei
This survey aims to give an overview of several substantial developments of the last 50 years in the structure theory of regular semigroups and to shed light on their impact on oth…
-inverse monoids as algebraic structures in enriched signature
K. Auinger, G. Kudryavtseva, M. B. Szendrei
Every -inverse monoid can be equipped with the unary operation which maps each element to the maximum element of its -class. In this enriched signature, the class of all -…
Inverse monoids of partial graph automorphisms
Robert Jajcay, Tatiana Jajcayova, Nóra Szakács +1
A partial automorphism of a finite graph is an isomorphism between its vertex induced subgraphs. The set of all partial automorphisms of a given finite graph forms an inverse monoi…
-solid locally inverse semigroups
Tamás Dékány, Mária B. Szendrei, István Szittyai
We prove that if is an -solid locally inverse semigroup, and is an inverse semigroup congruence on such that the idempotent classes of are completely simple semi…
Embedding in factorisable restriction monoids
Victoria Gould, Miklos Hartmann, Maria Szendrei
Each restriction semigroup is proved to be embeddable in a factorisable restriction monoid, or, equivalently, in an almost factorisable restriction semigroup. It is also establishe…
On F-inverse covers of finite-above inverse monoids
Nóra Szakács, Mária B. Szendrei
Finite-above inverse monoids are a common generalization of finite inverse monoids and Margolis--Meakin expansions of groups. Given a finite-above -unitary inverse monoid an…
