Title : Conjugacy class numbers and π-subgroups
We will discuss relations between the number of conjugacyclasses of a finite group and that of proper subgroups. On the way,we'll encounter the so-called almost abelian groups (a term coinedby J. Thompson). We then connect this to obtaining estimates for thenumber of Brauer characters in a Brauer block of a finite group.This is joint work with Gabriel Navarro and Geoffrey Robinson.
