On Fh-supplemented subgroups of finite groups

Resumo

Suppose that F is a formation of finite groups. We introduce the concept of F_h-supplemented subgroups and investigate the structure of finite groups on assuming that some maximal subgroups of Sylow subgroups, maximal subgroups, minimal subgroups, and 2-maximal subgroup are F_h-supplemented, respectively. Some available results are generalized.
