The prolongation of central extensions

Abstract

The aim of this paper is to study the (α,γ)(\alpha, \gamma)-prolongation of central extensions. We obtain the obstruction theory for (α,γ)(\alpha, \gamma)-prolongations and classify (α,γ)(\alpha, \gamma)-prolongations thanks to low-dimensional cohomology groups of groups.
