Factor system
text:
In mathematics, a factor system is a fundamental tool of Otto Schreier’s classical theory for group extension problem. It consists of a set of automorphisms and a binary function on a group satisfying certain condition. In fact, a factor system constitutes a realisation of the cocycles in the second cohomology group in group cohomology.
