有限维单实代数上除分次的分类

Classification of division gradings on finite-dimensional simple real algebras

Adrián Rodrigo-Escudero

摘要:

我们分类,同构和等价,司分级(阿贝尔群)有限维简单的实代数。有限维单代数上的分次是由除法分次决定的,所以我们的结果给出了这种代数上的分次(不一定是除法)的分类,直到同构。二元域上的线性代数在证明中起着有趣的作用。

英文摘要:

We classify, up to isomorphism and up to equivalence, division gradings (by abelian groups) on finite-dimensional simple real algebras. Gradings on finite-dimensional simple algebras are determined by division gradings, so our results give the classification, up to isomorphism, of (not necessarily division) gradings on such algebras. Linear algebra over the field of two elements plays an interesting role in the proofs.
