Variations on the Baer--Suzuki Theorem
arXiv:1310.5909
Abstract
The Baer--Suzuki theorem says that if is a prime, is a -element in a finite group and is a -group for all , then the normal closure of in is a -group. We consider the case where is replaced by for some other -element . While the analog of Baer--Suzuki is not true, we show that some variation is. We also answer a closely related question of Pavel Shumyatsky on commutators of conjugacy classes of -elements.
