Abstract:

By the positive solution to Ore's conjecture, every element of the commutator subgroup of a finite simple group is itself a commutator. This is far from being true in arbitrary finite groups, the easiest examples being given by finite p-groups, for a prime p. However, under some restrictions, the commutator subgroup of a finite p-group consists entirely of commutators. In this talk, we show that this is always the case if the commutator subgroup can be generated by 2 elements, thus generalising a result of Guralnick who reached the same conclusion with the extra assumption that the group is metabelian. This is joint work with Iker de las Heras.
