半交换$p$ -群的上同调性质

A cohomological property of semi-abelian $p$-groups

Mohammed T. Benmoussa, Yassine Guerboussa

摘要:

本文证明了M. Y. Xu,我们称之为半交换$p$ -群。这一结果意味着半交换$p$ -群具有$p$阶的非内自同构,从而解决了该类的一个长期问题。我们还独立地回答了M. Y. Xu关于半交换$p$ -群的幂结构.

英文摘要:

We prove a cohomological property for a class of finite $p$-groups introduced earlier by M. Y. Xu, which we call semi-abelian $p$-groups. This result implies that a semi-abelian $p$-group has non-inner automorphisms of order $p$, which settles a longstanding problem for this class. We answer also, independetly, an old question of M. Y. Xu about the power structure of semi-abelian $p$-groups.
