Abstract:
Throughout the article, all groups are finite and $G$ always denotes a finite group. Moreover, $\sigma$ is some partition of the set of all
primes $\mathbb{P}$, i. e. $\sigma=\{\sigma_i\mid i\in I\}$, where $\mathbb{P}=\bigcup_{i\in I}\sigma_i$ and $\sigma_i\cap\sigma_j=\varnothing$ for all $i\ne j$. A $\sigma$-property of a group is any of its
properties that do not depend on the choice of the partition $\sigma$ of the set $\mathbb{P}$. This work is devoted to further the study of the
$\sigma$-properties of a group. A lot of known results are generalized.
Keywords:
finite group, $\sigma$-nilpotent group, $\sigma$-soluble group, $\sigma$-subnormal subgroup, Schmidt group.
