Álgebra de Clifford: classificações e representações

Abstract

In this paper, we study Clifford algebras so universal and constructive as quantization of exterior algebra, we classify all Clifford algebras associated with the quadratic Minkowski spaces (Rp+q, p,q), where p,q(u) = u21 +...+u2 p −(u2 p+1 +...+u2 p+q), u = (u1, ..., up+q) ∈ Rp+q, which we denote by Clp,q, as well as their complexifications. To do so, we use important results as the periodicity theorem Carton / Bott. The, we study their representations, emphasizing the Twisted Adjoint Representataion, Spin Representation and the Spin-Half Representation moreover using the number of Radon-Hurwitz we study representations of the algebras Cl0,k.
