On $H_{σ}$ -permutably embedded and $H_{σ}$ -subnormaly embedded subgroups of finite groups

Wenbin Guo, Chi Zhang, Alexander N. Skiba +1

Let $G$ be a finite group. Let $σ = {σ_{i} ∣ i \in I}$ be a partition of the set of all primes $P$ and $n$ an integer. We write $σ (n) = {σ_{i} ∣ σ_{i} \cap π (n) \neq = \emptyset}$ …

On weakly $s i g ma$ -permutable subgroups of finite groups

Chi Zhang, Zhenfeng Wu, W. Guo

Let G be a finite group and σ = {σ_i, i \in I} be a partition of the set of all primes \mathbb{P}. A set \mathcal{H} of subgroups of G with 1 \in \mathcal{H} is said to be a comple…
