Bott type periodicity for the higher octonions

Abstract

We study the series of complex nonassociative algebras On and real nonassociative algebras $O_{p,q}$ introduced in [10]. These algebras generalize the classical algebras of octonions and Clifford algebras. The algebras $O_n$ and $O_{p,q}$ with $p+q=n$ have a natural $Z_n^2$-grading, and they are characterized by cubic forms over the field $Z_2$. We establish a periodicity for the algebras $O_n$ and $O_{p,q}$ similar to that of the Clifford algebras Cln and $C{l}_{p,q}$.
