Solvability of unimodular equations in groups and Lie algebras

Anton A. Klyachko, Mikhail A. Mikheenko, Alexander Yu. Olshanskii

Our results implies, in particular, that a finitely generated solvable group is nilpotent if and only if it contains a solution to any unimodular equation, i.e., an equation of…

Invariant covers of multipartite hypergraphs

Anton A. Klyachko, Mikhail S. Terekhov

We prove the following ``symmetric analogue'' of Lovász's estimate (1975): if an -partite hypergraph of rank has a cover of cardinality , then it admits…

Equationally separable classes of groups

Alexander Buturlakin, Anton Klyachko, Denis Osin

Over each nontrivial finite group , there exists a finite system of equations having no solutions in larger finite groups but having a solution in a periodic group containing $G…

Forester's lattices and small non-Leighton complexes

Natalia S. Dergacheva, Anton A. Klyachko

We construct two CW-complexes and admitting a common, but not finite common, covering, where is homeomorphic to a complex with a single 2-cell.

Finite symmetric groups are strongly verbally closed

Olga K. Karimova, Anton A. Klyachko

Answering a question of A. V. Vasil'ev, we show that each finite symmetric (or alternating) group is a retract of any group containing as a verbally closed subgroup.

Tiny non-Leighton complexes

Natalia S. Dergacheva, Anton A. Klyachko

How complex must two finite 2-complexes be to admit a common, but not finite common, covering? We obtain an almost answer: the minimum possible number of triangles in a pseudo-simp…
