On group gradings on PI-algebras
Eli Aljadeff, Ofir David
We show that there exists a constant K such that for any PI- algebra W and any nondegenerate G-grading on W where G is any group (possibly infinite), there exists an abelian subgro…
The center of the generic G-crossed product
Ofir David
Let G be a finite group and let F be a field of characteristic zero. In this paper we construct a generic G-crossed product over F using generic graded matrices. The center of this…
On regular G-grading
Eli Aljadeff, Ofir David
Let A be an associative algebra over an algebraically closed field F of characteristic zero and let G be a finite abelian group. Regev and Seeman introduced the notion of a regular…
Graded Embeddings of Finite Dimensional Simple Graded Algebras
Ofir David
Let A,B be finite dimensional G-graded algebras over an algebraically closed field K with char(K)=0, where G is an abelian group, and let Id_G(A) be the set of graded identities of…
