Supernilpotent Semigroups
Jelena Radović, Nebojša Mudrinski
Regular abelian semigroups are isomorphic to a direct product of an abelian group and a rectangular band (Warne, 1994). Seeking for a similar result for nilpotency, solvability and…
Commutators in Completely Simple Semigroups
Jelena Radović, Nebojša Mudrinski
We obtain a characterization of the binary commutator on completely simple semigroups, using their Rees matrix representation. Consequently, we prove that a regular semigroup is ni…
Complexity of term representations of finitary functions
Erhard Aichinger, Nebojša Mudrinski, Jakub Opršal
The clone of term operations of an algebraic structure consists of all operations that can be expressed by a term in the language of the structure. We consider bounds for the lengt…
On the Dual Ramsey Property for Finite Distributive Lattices
Dragan Masulovic, Nebojsa Mudrinski
The class of finite distributive lattices, as many other classes of structures in everyday use, does not have the Ramsey property. It is quite common, though, that after expanding…
Finite generation of congruence preserving functions
Erhard Aichinger, Marijana Lazić, Nebojša Mudrinski
We investigate when the clone of congruence preserving functions is finitely generated. We obtain a full description for all finite -groups, and for all finite algebras with Mal…
Sequences of commutator operations
Erhard Aichinger, Nebojsa Mudrinski
Given the congruence lattice L of a finite algebra A with a Mal'cev term, we look for those sequences of operations on L that are sequences of higher commutator operations of expan…
