Part of the book series: Trends in Mathematics ((TM))

Abstract

We obtain an upper bound for the dimension of the first cohomology group of a finite group acting faithfully and irreducibly on a finite dimensional module. We discuss the connection between results of this nature and generation questions for finite simple groups.
