由群代数的扭曲得到的Clifford代数

Clifford algebras obtained by twisting of group algebras

H. Albuquerque, S. Majid

摘要:

我们研究Clifford代数的构造和性质,其方法与我们以前构造八元数的方法类似,即把Z_2 ^n的群代数用一个上圈扭曲。我们的方法比通常的基于生成元和关系的方法更一般。特别地,我们得到了Clifford代数中旋量的周期性和一个新的构造。

英文摘要:

We investigate the construction and properties of Clifford algebras by a similar manner as our previous construction of the octonions, namely as a twisting of group algebras of Z_2^n by a cocycle. Our approach is more general than the usual one based on generators and relations. We obtain in particular the periodicity properties and a new construction of spinors in terms of left and right multiplication in the Clifford algebra.
