报告题目:Finite groups with pronormality in maximal subgroups of even order
报 告 人: 刘建军
报告摘要:Let G be a finite group. A subgroup H of a group G is called pronormal in G if the subgroups H and Hg are conjugate in ⟨H, Hg⟩ for each g∈G. This talk investigates groups G in which every maximal subgroup of even order is a PRN-group-that is, all of its minimal subgroups (of prime order or order 4) are pronormal. We establish that any such group G, if it is itself a non-PRN-group, must be solvable and its order can be divisible by at most three distinct primes. Furthermore, a complete structural characterization is provided.
