Previous issue date: 2013-08-30 === Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES === 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. === Neste trabalho, estudamos as ´algebras de Clifford Cl(V, ) associadas aos espa¸cos quadr´aticos
(V, ), de maneira universal, construtiva e como quantiza¸c˜ao da ´algebra exterior. Classificamos

as quais denotamos por Clp,q, bem como suas complexifica¸c˜oes. Para tanto, usaremos
resultados importantes como o teorema da periodicidade de Carton/Bott. Al´em disso,
estudamos as suas representa¸c˜oes, destacando a Representa¸c˜ao Adjunta Torcida, as Representa
¸c˜oes Spin e Semi-Spin e por meio do n´umero de Radon-Hurwitz estudamos as
representa¸c˜oes das ´algebras Cl0,k.
