Crossed product of groups. Applications

Published 2008-05-27, updated 2008-08-11Version 2

We survey the extensions of a group by a group using crossed products instead of exact sequences of groups. The approach has various advantages, one of them being that the crossed product is an universal object. Several new applications are given, a general Schreier type theorem is proved and a few open problems are left.

Comments: Final version. To appear in AJSE
