Central Simple Zd-graded Algebras

In [W], C.T.C. Wall established the theory of central simple Z2-graded algebras and recently in [K-Ku] C.Koç and Y. Kurtulmaz investigated the structure of Bbb Zd-graded algebras and established decomposition theorems for central simple Zp-graded algebras when p is a prime number. In this paper we extend these decomposition theorems to Zd-graded algebras for an arbitrary integer d and as an application we give the complete structure theory of generalized Clifford algebras. We also provide a short proof to the decomposition results given by T.L. Smith in [S].
