چکیده

One of the main directions in group theory is study impact characteristic subgroups on structure whole group. Such include different $\Sigma$-norms a A $\Sigma$-norm intersection normalizers all system $\Sigma$. The authors non-periodic groups with restrictions such -- norm $N_{G}(C_{\bar{p}})$ cyclic non-prime order, which composite or infinite order $G$. It was proved that if $G$ mixed group, then its either Abelian (torsion non-periodic) non-Abelian. Moreover, has non-Abelian $N_{G}(C_{\bar{p}})$of and only every subgroup normal it, $G=N_{G}(C_{\bar{p}})$.Additionally relations between $N_{G}(C_{\infty})$ subgroups, are studied. found norms $N_{G}(C _{\infty})$ _{\bar{p}})$ coincide contains elements does not contain non-normal 4.In this case $N_{G}(C_{\bar {p}})=N_{G}(C_{\infty})=G$.

Finite groups with $X$-quasipermutable subgroups of prime power order

Let $H$, $L$ and $X$ be subgroups of a finite group$G$. Then $H$ is said to be $X$-permutable with $L$ if for some$xin X$ we have $AL^{x}=L^{x}A$. We say that $H$ is emph{$X$-quasipermutable } (emph{$X_{S}$-quasipermutable}, respectively) in $G$ provided $G$ has a subgroup$B$ such that $G=N_{G}(H)B$ and $H$ $X$-permutes with $B$ and with all subgroups (with all Sylowsubgroups, respectively) $...

Finite $p$-groups and centralizers of non-cyclic abelian subgroups

A $p$-group $G$ is called a $mathcal{CAC}$-$p$-group if $C_G(H)/H$ is ‎cyclic for every non-cyclic abelian subgroup $H$ in $G$ with $Hnleq‎ ‎Z(G)$‎. ‎In this paper‎, ‎we give a complete classification of‎ ‎finite $mathcal{CAC}$-$p$-groups‎.

The number of Fuzzy subgroups of some non-abelian groups

In this paper, we compute the number of fuzzy subgroups of some classes of non-abeilan groups. Explicit formulas are givenfor dihedral groups $D_{2n}$, quasi-dihedral groups $QD_{2^n}$, generalized quaternion groups $Q_{4n}$ and modular $p$-groups $M_{p^n}$.
