Green’s Relations on Submonoids of Generalized Hypersubstitutions of Type (n)
Discussiones Mathematicae - General Algebra and Applications, 2021 A generalized hypersubstitution of type τ = (n) is a function which takes the n-ary operation symbol f to the term of the same type σ(f ) which does not necessarily preserve the arity. Let HypG(n) be the set of all these generalized hypersubstitutions of

All Maximal Completely Regular Submonoids of HypG(2)
Discussiones Mathematicae - General Algebra and Applications, 2017 In this paper we consider mappings σ which map the binary operation symbol f to the term σ (f) which do not necessarily preserve the arity. These mapping are called generalized hypersubstitutions of type τ = (2) and we denote the set of all these ...

Absolute Retracts as Reduced Products
, 2004 We show that in finitely generated congruence distributive varieties every absolute retract is a product of reduced powers of maximal subdirectly irreducibles.

Dominions In Varieties Of Nilpotent Groups
. We investigate the concept of dominion (in the sense of Isbell) in several varieties of nilpotent groups. We obtain a complete description of dominions in the variety of nilpotent groups of class at most two.
