Finite and nilpotent strongly verbally closed groups
Anton A. Klyachko, Veronika Yu. Miroshnichenko, Alexander Yu. Olshanskii
We show, in particular, that, if a finite group is a retract of any finite group containing as a verbally closed subgroup, then the centre of is a direct factor of .
Small non-Leighton two-complexes
Natalia S. Dergacheva, Anton A. Klyachko
How many two-cells must two finite CW-complexes have to admit a common, but not finite common, covering? Leighton's theorem says that both complexes must have two-cells. We constru…
An analogue of the strengthened Hanna Neumann conjecture for virtually free groups and virtually free products
Anton A. Klyachko, Alexander O. Zakharov
The Friedman--Mineyev theorem, earlier known as the (strengthened) Hanna Neumann conjecture, gives a sharp estimate for the rank of the intersection of two subgroups in a free grou…
