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 $N_{G}(C_{\bar {p}})=N_{G}(C_{\infty})=G$.

15 صفحه اولFinite 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) $...
متن کاملFinite $p$-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.
متن کاملOn non-normal non-abelian subgroups of finite groups
In this paper we prove that a finite group $G$ having at most three conjugacy classes of non-normal non-abelian proper subgroups is always solvable except for $Gcong{rm{A_5}}$, which extends Theorem 3.3 in [Some sufficient conditions on the number of non-abelian subgroups of a finite group to be solvable, Acta Math. Sinica (English Series) 27 (2011) 891--896.]. Moreover, we s...
متن کاملThe 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 $M_{p^n}$.
