On groups with many normal subgroups [PDF]
International Journal of Group Theory, 2023 The structure of groups which are rich in normal subgroups has been investigated by several authors. Here, we prove that if a radical group G has normal deviation, which means that the set of its non-normal subgroups satisfies a very weak chain condition,

On algebraic aspects of η-fuzzy subgroups [PDF]
Journal of Fuzzy Extension and Applications, 2023 In this paper, we define the term " η-fuzzy subgroup" and show that every fuzzy subgroup is a η-fuzzy subgroup. We define some of the algebraic properties of the concept of η-fuzzy cosets. Furthermore, we initiate the study of the η-fuzzy normal subgroup

Pronormality in Group Theory [PDF]
Advances in Group Theory and Applications, 2020 A subgroup X of a group G is said to be pronormal if for each element g of G the subgroups X and X^g are conjugate in . The aim of this paper is to study pronormality and some close embedding properties, like weak normality and weak pronormality.

Generalized Pythagorean Neutrosophic Sets in the Study of Group Theory [PDF]
Neutrosophic Sets and Systems, 2021 In 2019, Jansi et al. present the notion of the Pythagorean neutrosophic set (PNS) as an extension of a neutrosophic set with dependent neutrosophic components. But due to the more complexity involved in a decision-making problem, there is a serious need

An algebraic analysis on exploring q-Rung orthopair multi-fuzzy sets [PDF]
Journal of Fuzzy Extension and Applications, 2023 The q-Rung Orthopair Fuzzy set (qROF-set) environment is a contemporary tool for handling uncertainty and vagueness in decision-making scenarios. In this paper, we delve into the algebraic examination of q-rung orthopair Multi-Fuzzy Sets (MFSs) and ...

Conjugate L-subgroups of An L-group and Their Applications to Normality and Normalizer
Fuzzy Information and Engineering, 2022 In this paper, the notion of the conjugate of an L-subgroup by an L-point has been introduced. Then, several properties of conjugate L-subgroups have been studied analogous to their group-theoretic counterparts.

Structure of intersection graphs
Indonesian Journal of Combinatorics, 2021 Let G be a finite group and let N be a fixed normal subgroup of G. In this paper, a new kind of graph on G, namely the intersection graph is defined and studied.

Karpatsʹkì Matematičnì Publìkacìï, 2021 A group $G$ has a finite special rank $r$ if every finitely generated subgroup of $G$ is generated by at most $r$ elements and there is a finitely generated subgroup of $G$ which has exactly $r$ generators.

Groups with Finitely Many Isomorphism Classes of Non-Normal Subgroups [PDF]
Advances in Group Theory and Applications, 2020 We study groups in which the non-normal subgroups fall into finitely many isomorphism classes. We prove that a locally generalized radical group with this property is abelian-by-finite and minimax.

Self-normalizing Sylow subgroups [PDF]
Proceedings of the American Mathematical Society, 2003 Using the classification of finite simple groups we prove the following statement: Let p > 3 p>3 be a prime, Q Q a group of automorphisms of p p -power order of a finite group G G , and P P a Q Q -invariant Sylow
