Web16 de nov. de 2024 · A subgroup H of G is called weakly normal in G if H^ {x}\le N_ {G} (H) implies that H=H^ {x}, where x\in G. Here we prove that for p -subgroups of finite groups, the concept of pronormal subgroups, weakly normal subgroups and weakly closed subgroups are equivalent. Theorem 4.3 Web3 de jun. de 2016 · We say that H is weakly ℋ -embedded in G if G has a normal subgroup K such that HG = HK and H ∩ K is an ℋ-subgroup in G. In this paper, we investigate the …

On weakly $sigma$-permutable subgroups of finite groups

Web23 de set. de 2024 · The best and standard way to prove it is to consider the map from H × K to HK which sends (h, k) to hk and look at the equivalence classes of pairs mapped to the same element of HK. That is for every (h, k) count pairs (h ′, k ′) such that hk = h ′ k ′. Edit To make it complete, hk = h ′ k ′ is equivalent to h − 1h ′ = k ′ k − 1.
