Symmetric cohomology of groups

open access: yes, 2017
We investigate the relationship between the symmetric, exterior and classical cohomologies of groups. The first two theories were introduced respectively by Staic and Zarelua.

Finite groups which are the products of symmetric or alternating groups with $L_3(4)$ [PDF]

open access: yesInternational Journal of Group Theory, 2016
In this paper‎, ‎we determine the simple groups $G=AB$‎, ‎where $B$ is isomorphic to $L_{3}(4)$ and $A$ isomorphic to an alternating or a symmetric group on $n\geq5$‎, ‎letters‎.

Spin characters of generalized symmetric groups

open access: yes, 2013
In 1911 Schur computed the spin character values of the symmetric group using two important ingredients: the first one later became famously known as the Schur Q-functions and the second one was certain creative construction of the projective characters ...

Symmetric Groups and Quotient Complexity of Boolean Operations [PDF]

open access: yes, 2013
The quotient complexity of a regular language L is the number of left quotients of L, which is the same as the state complexity of L. Suppose that L and L' are binary regular languages with quotient complexities m and n, and that the transition ...

Maximal 3-local subgroups of symmetric groups [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2013
The subgroups in the set max    G B, consisting of all maximal 3-local subgroups of G Sym n  ( ) with respect to B,the normalizer of a Sylow 3-subgroup of G in G, is investigated.

Admissible groups, symmetric factor sets, and simple algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Let K be a field of characteristic zero and suppose that D is a K-division algebra; i.e. a finite dimensional division algebra over K with center K. In Mollin [1] we proved that if K contains no non-trivial odd order roots of unity, then every finite odd

Subgroups of Infinite Symmetric Groups

open access: yesJournal of the London Mathematical Society, 1990
Various questions are discussed on the subgroup structure of \(S:=Sym(\Omega)\), where \(\Omega\) is an infinite set. It is shown that S is not the union of a chain of size \(| \Omega |\) of proper subgroups, and results are obtained on the size of the smallest families of proper subgroups with set-theoretic union S.

Symmetric groups and checker triangulated surfaces

open access: yes, 2017
We consider triangulations of surfaces with edges painted three colors so that edges of each triangle have different colors. Such structures arise as Belyi data (or Grothendieck dessins d'enfant), on the other hand they enumerate pairs of permutations ...

Comparison of Gelfand-Tsetlin Bases for Alternating and Symmetric Groups [PDF]

open access: yes, 2017
Young's orthogonal basis is a classical basis for an irreducible representation of a symmetric group. This basis happens to be a Gelfand-Tsetlin basis for the chain of symmetric groups. It is well-known that the chain of alternating groups, just like the
