On units in group algebras

Abstract

Our aim was to study the relation between the derived length of the group of units in a group algebra of a finite group over a field of positive characteristic and the commutativity of the group We have mostly studied group algebras with their unit groups having derived length at most four and proved their commutativity when the characteristic of the field p is greater than or equal to seventeen We also prove commutativity of G when the derived length of U is smaller than upper integer part of
