Let F be an algebraically closed field of characteristic zero and let G be a finite group. In this paper we will show that the asymptotics of c G n (A), the Ggraded codimension sequence of a finite dimensional G-simple F -algebra A, has the form αn 1−dim F Ae 2 (dim F A) n (as conjectured by E.Aljadeff, D.Haile and M. Natapov), where α is some positive real number and A e denotes the identity component of A. In the special case where A is the algebra of m×m matrices with an arbitrary elementary G-grading we succeeded in calculating the constant α explicitly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
