Mesomorphic Behavior of Symmetric Azomethine Dimers Containing Different Chromophore Groups

open access: yesMolecules, 2021
A series of new azomethine dimers was synthesized by the condensation reaction of flexible bis-benzaldehydes with four aromatic amines containing phenyl, naphthyl, anthracene and pyrene groups.

QUANTUM ISOMETRY GROUPS OF SYMMETRIC GROUPS [PDF]

open access: yesInternational Journal of Mathematics, 2012
We identify the quantum isometry groups of spectral triples built on the symmetric groups with length functions arising from the nearest-neighbor transpositions as generators. It turns out that they are isomorphic to certain "doubling" of the group algebras of the respective symmetric groups.

An algorithm for generating permutation algebras using soft spaces

open access: yesJournal of Taibah University for Science, 2018
Soft set theory has recently gained significance for finding rational and logical solutions to various real-life problems, which involve uncertainty, impreciseness and vagueness.

Permutation codes over Sylow 2-subgroups $Syl_2(S_{2^n})$ of symmetric groups $S_{2^n}$

open access: yesResearches in Mathematics, 2021
The permutation code (or the code) is well known object of research starting from 1970s. The code and its properties is used in different algorithmic domains such as error-correction, computer search, etc.

Invariants in Non-Commutative Variables of the Symmetric and Hyperoctahedral Groups [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We consider the graded Hopf algebra $NCSym$ of symmetric functions with non-commutative variables, which is analogous to the algebra $Sym$ of the ordinary symmetric functions in commutative variables.

Factorization of groups involving symmetric and alternating groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We obtain the structure of finite groups of the form G=AB where B is a group isomorphic to the symmetric group on n letters Sn, n≥5 and A is a group isomorphic to the alternating group on 6 letters.

SOFT INTERSECTION-SYMMETRIC DIFFERENCE PRODUCT OF GROUPS [PDF]

open access: yesMatrix 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 ...

Homogenous finitary symmetric groups [PDF]

open access: yesInternational 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 =

On the Genus of Symmetric Groups [PDF]

open access: yesTransactions of the American Mathematical Society, 1981
A new method for determining genus of a group is described. It involves first getting a bound on the sizes of the generating set for which the corresponding Cayley graph could have smaller genus. The allowable generating sets are then examined by methods of computing average face sizes and by voltage graph techniques to find the best embeddings.
