实Clifford代数的复结构

Complex structure of a real Clifford algebra

Jason Hanson

摘要:

实Clifford代数的矩阵代数分类是众所周知的。在这里,我们考虑实Clifford代数${\mathcal Cl}(r,s)$不是作为矩阵代数,而是作为自身上的Clifford模。我们证明了只有当体积元$ω$的平方为-1时,${\mathcal Cl}(r,s)$才具有基独立复结构,在这种情况下,它唯一地放弃与$ω$的右乘符号.

英文摘要:

The classification of real Clifford algebras in terms of matrix algebras is well--known. Here we consider the real Clifford algebra ${\mathcal Cl}(r,s)$ not as a matrix algebra, but as a Clifford module over itself. We show that ${\mathcal Cl}(r,s)$ possesses a basis independent complex structure only when the square of the volume element $ω$ is -1, in which case it is uniquely given up to sign by right multiplication with $ω$.
