On a generalization of Shmel'kin's theorem
Mikhail A. Mikheenko
It is known that every nilpotent group contains solution of every finite unimodular system of equatiuons over itself. This statement, however, is not true for infinite systems. Mor…

Infinite systems of equations in abelian and nilpotent groups
Mikhail A. Mikheenko
Every abelian (and even every nilpotent) group contains a solution of any finite unimodular system of equations over itself. However, this is not true for infinite systems. We dedu…

Unimodular equations which do not preserve the derived length of a group
Mikhail A. Mikheenko
It is a known fact that any unimodular equation over an abelian group has a solution in that group itself. It is also known that for metabelian groups this does not hold; moreover,…
