On $\sigma$-$c$-subnormal subgroups of finite groups
Let $ \sigma=\{\sigma_i:i\in I\} $ be a partition of the set $ \mathbb{P} $ of all primes. A finite group $ G $ is called $ \sigma $-primary if the prime divisors, if any, of $|G|$ all belong to the same member of $ \sigma $. A finite group $ G $ is called $ \sigma $-soluble if every chief factor of $ G $ is $ \sigma$-primary. A subgroup $H$ of a group $G$ is called $\sigma$-subnormal in $G$ if there is a chain of subgroups $H=H_0\leq H_1\leq\cdots\leq H_n=G$ such that either $ H_{i-1} $ is normal in $ H_i $ or $ H_{i}/(H_{i-1})_{H_{i}} $ is $ \sigma $-primary for all $ i=1,\dots,n $; A subgroup $H$ of a group $G$ is called $\sigma$-$c$-subnormal in $G$ if there is a subnormal subgroup $T$ of $G$ such that $G=HT$ and $H\cap T\leq H_{\sigma G}$, where the subgroup $H_{\sigma G}$ is generated by all $\sigma$-subnormal subgroups of $G$ contained in $H$. In this paper, we investigate the influence of $\sigma$-$c$-subnormality of some kinds of maximal
subgroups on $\sigma$-solubility of finite groups, which generalize some known results.
期刊介绍:
Hacettepe Journal of Mathematics and Statistics covers all aspects of Mathematics and Statistics. Papers on the interface between Mathematics and Statistics are particularly welcome, including applications to Physics, Actuarial Sciences, Finance and Economics.
We strongly encourage submissions for Statistics Section including current and important real world examples across a wide range of disciplines. Papers have innovations of statistical methodology are highly welcome. Purely theoretical papers may be considered only if they include popular real world applications.
