Schur Algebras for the Alternating Group and Koszul Duality
, 2020 We introduce the alternating Schur algebra $AS_F(n,d)$ as the commutant of the action of the alternating group $A_d$ on the $d$-fold tensor power of an $n$-dimensional $F$-vector space.

Non-Nudgable Subgroups of Permutations [PDF]
, 2017 Motivated by a problem from behavioral economics, we study subgroups of permutation groups that have a certain strong symmetry. Given a fixed permutation, consider the set of all permutations with disjoint inversion sets. The group is called non-nudgable,

Product of Conjugacy Classes of the Alternating Group An
مجلة بغداد للعلوم, 2012 For a nonempty subset X of a group G and a positive integer m , the product of X , denoted by Xm ,is the set Xm = That is , Xm is the subset of G formed by considering all possible ordered ...

Conditional Strong Matching Preclusion of the Alternating Group Graph
Theory and Applications of Graphs, 2019 The strong matching preclusion number of a graph is the minimum number of vertices and edges whose deletion results in a graph that has neither perfect matchings nor almost-perfect matchings.

Alternating Groups and Latin Squares
European Journal of Combinatorics, 1989 The question studied here is, whether the alternating group on n symbols, \({\mathcal A}(n)\), can be the multiplication group of a loop. Let \({\mathcal M}_{\ell}\) and \({\mathcal M}_ r\), respectively, be the left and right multiplication groups of a loop, and let \({\mathcal M}:={\mathcal M}_{\ell}\cup {\mathcal M}_ r\).

WHICH ALTERNATING AND SYMMETRIC GROUPS ARE UNIT GROUPS? [PDF]
Journal of Algebra and Its Applications, 2013 We prove there is no ring with unit group isomorphic to Sn for n ≥ 5 and that there is no ring with unit group isomorphic to An for n ≥ 5, n ≠ 8. To prove the non-existence of such a ring, we prove the non-existence of a certain ideal in the group algebra 𝔽2[G], with G an alternating or symmetric group as above.

Noncommutative Riemannian Geometry of the Alternating Group A_4
, 2001 We study the noncommutative Riemannian geometry of the alternating group $A_4=(Z_2 \times Z_2)\cross Z_3$ using a recent formulation for finite groups.
