Conjugacy classes of $\pi$-elements and nilpotent/abelian Hall $\pi$-subgroups

Nguyen N. Hung, Attila Maróti and Juan Martínez

Vol. 323 (2023), No. 1, 185–204
DOI: 10.2140/pjm.2023.323.185
Abstract

Let G be a finite group and π be a set of primes. We study finite groups with a large number of conjugacy classes of π-elements. In particular, we obtain precise lower bounds for this number in terms of the π-part of the order of G to ensure the existence of a nilpotent or abelian Hall π-subgroup in G.

Keywords
finite groups, conjugacy classes, $\pi$-elements, Hall subgroups.
