Closed Normal Subgroups

MLQ, 2001
The paper gives a new, shorter proof of an important theorem of Richard Kaye: closed normal subgroups of the automorphism group of a countable recursively saturated model of Peano Arithmetic are exactly the pointwise stabilizers of invariant initial segments which are closed under exponentiation [\textit{R.

The lattices of fuzzy subgroups and fuzzy normal subgroups

Information Sciences, 1994
The paper deals with fuzzy subgroups and fuzzy normal subgroups of a given group [cf. \textit{I. J. Kumar, P. K. Saxena, P. Yadav}, Fuzzy Sets Syst. 46, 121-132 (1992; Zbl 0776.20025)]. The main result of this paper is a special case of Theorem 3.8 and Remark 3.9 of \textit{M. Mashinchi, Sh. Salili, M. M. Zahedi} [Bull. Iran. Math. Soc. 18, 17-29 (1992;

On Normal Embedding of Subgroups

Geometriae Dedicata, 2000
The author surveys conditions for a group to allow an embedding as a normal subgroup of another finite group, with an additional condition of containment in some given characteristic subgroup. The main objects of the article are finite groups. Let \(\Aut_c(G)\) denote the group of all central automorphisms of a group \(G\), \(\text{Inn}_c(G)=\Aut_c(G ...

Subgroups normalized by the elementary Levi subgroup

Journal of Mathematical Sciences, 2006
Subgroups of the unipotent radical of a maximal parabolic subgroup of a Chevalley group over a field K, which are normalized by the commutator subgroup of the Levi subgroup, are described. It is shown that in the typical case, such subgroups are in one-to-one correspondence with the closed subsets of {1, 2, ..., n} for a natural n.

On the distribution of subgroups normalized by a given subgroup

Journal of Soviet Mathematics, 1993
A whole series of results on the distribution of subgroups containing a given subgroup or normalized by a given subgroup is subject to a single principle. Namely, a whole lattice of subgroups under consideration is divided into intervals in such a manner that the factorgroup of the upper bound of each interval by the lower one provides complete ...

Normalizers of subgroups of division rings

Journal of Group Theory, 2008
Let \(D\) be a division ring with centre \(F\), \(G\) be a subgroup of the multiplicative group \(D^*\) of \(D\). Denote by \(H=N_{D^*}(G)\) the normalizer of \(G\) in \(D^*\) and by \(E=C_D(G)\) the centralizer of \(G\) in \(D\). \textit{M. Shirvani}, [in J. Algebra 294, No. 1, 255-277 (2005; Zbl 1088.16024)], was able to compute \(H\) precisely for \(
