Brauer's problem 21 for principal blocks

Alexander Moretó, Noelia Rizo, A. A. Schaeffer Fry

Problem 21 of Brauer's list of problems from 1963 asks whether for any positive integer k there are finitely many isomorphism classes of groups that occur as the defect group of a…

Prime divisors and the number of conjugacy classes of finite groups

Thomas Michael Keller, Alexander Moretó

We prove that there exists a universal constant such that if is a prime divisor of the index of the Fitting subgroup of a finite group , then the number of conjugacy cla…

The codegree isomorphism problem for finite simple groups

Nguyen N. Hung, Alexander Moretó

We study the codegree isomorphism problem for finite simple groups. In particular, we show that such a group is determined by the codegrees (counting multiplicity) of its irreducib…
