Abstract

We define a general notion of centrally Γ\Gamma-graded sets and groups and of their graded products, and prove some basic results about the corresponding categories: most importantly, they form braided monoidal categories. Here, Γ\Gamma is an arbitrary (generalized) ring. The case Γ\Gamma = Z/2Z is studied in detail: it is related to Clifford algebras and their discrete Clifford groups (also called Salingaros Vee groups).
