An inductive method for separable deformations
Yuval Ginosar, Ariel Amsalem
The Donald-Flanigan conjecture asserts that any group algebra of a finite group has a separable deformation. We apply an inductive method to deform group algebras from deformations…
Quotient gradings and the intrinsic fundamental group
Yuval Ginosar, Ofir Schnabel
Quotient grading classes are essential participants in the computation of the intrinsic fundamental group of an algebra . In order to study quotient gradings of a finit…
Mackey's obstruction map for discrete graded algebras
Yuval Ginosar
G.W. Mackey's celebrated obstruction theory for projective representations of locally compact groups was remarkably generalized by J. M. G. Fell and R. S. Doran to the wide area of…
Realization-obstruction exact sequences for Clifford system extensions
Yuval Ginosar
For every action of a group on a commutative ring we introduce two abelian monoids. The monoid consists of equivalen…
Separable deformations of the generalized quaternion group algebras
Yuval Ginosar
The group algebras of the generalized quaternion groups over fields which contain , are deformed to separable -algebras $[kQ_…
Crossed Products and Coding Theory
Yuval Ginosar, Aviram Rochas Moreno
Families of codes such as group codes, constacyclic and skew cyclic codes, some of which independently suggested in the literature, turn out to be special instances of the general…
