SOFT INTERSECTION-SYMMETRIC DIFFERENCE PRODUCT OF GROUPS [PDF]

Matrix Science Mathematic
Soft set theory constitutes a mathematically robust and structurally versatile formalism for modeling real-world systems characterized by epistemic uncertainty, vagueness, and parameter-contingent variability—ubiquitous features across decision theory ...

Group codes over symmetric groups

AIMS Mathematics, 2023
<abstract><p>Let $ \Bbb F_{q} $ be a finite field of characteristic $ q $ and $ S_n $ a symmetric group of order $ n! $. In this paper, group codes in the symmetric group algebras $ \Bbb F_{q}S_n $ with $ q &gt; 3 $ and $ n = 3, 4 $ are proposed.

Homogenous finitary symmetric groups [PDF]

International Journal of Group Theory, 2015
We characterize strictly diagonal type of embeddings of finitary symmetric groups in terms of cardinality and the characteristic. Namely, we prove the following. Let kappa be an infinite cardinal. If G=underseti=1stackrelinftybigcupG i , where G i =

Double cyclotomic symmetric groups

Journal of Algebra, 2005
This paper considers the structure and representation theory of certain finite dimensional quotients \(H_r\) of the toroidal symmetric groups. The authors prove that \(H_r\) is a cellular algebra by constructing a cellular basis for \(H_r\). Permutation modules and corresponding endomorphism algebras for \(H_r\) are also studied.

The group of endotrivial modules for the symmetric and alternating groups. [PDF]

, 2010
We complete a classification of the groups of endotrivial modules for the modular group algebras of symmetric groups and alternating groups. We show that, for n ≥ p2, the torsion subgroup of the group of endotrivial modules for the symmetric groups is ...

The Tropical Matrix Groups with Symmetric Idempotents

Discrete Dynamics in Nature and Society, 2018
In this paper we study the semigroup Mn(T) of all n×n tropical matrices under multiplication. We give a description of the tropical matrix groups containing a diagonal block idempotent matrix in which the main diagonal blocks are real matrices and other ...

Endotrivial modules for the symmetric and alternating groups. [PDF]

, 2009
In this paper we determine the group of endotrivial modules for certain symmetric and alternating groups in characteristic $p$. If $p=2$, then the group is generated by the class of $\Omega^n(k)$ except in a few low degrees.

Automorphism groups of some families of bipartite graphs

Electronic Journal of Graph Theory and Applications, 2021
This paper discusses the automorphism group of a  class of  weakly semiregular bipartite graphs and its subclass called WSBEND graphs.  It also tries to analyse the  automorphism group of the SM sum graphs and SM balancing graphs.
