Title: On an inverse problem to Frobenius’s theorem
Abstract: Let G be a finite group and e a positive integer dividing |G|, the order of G.
Denoting Le(G) = {x \in G| xe = 1}, Frobenius proved that |Le(G)| = ke for a
positive integer k ≥ 1. In this talk, we give a complete classification of finite groups
G with |Le(G)| ≤ 2e for every e dividing |G|.
