单经典李代数的精细分次

Fine gradings on simple classical Lie algebras

Alberto Elduque

摘要:

在特征为0的代数闭域上的简单经典李代数(包括D4)上等价地确定了细阿贝尔群分次。这是通过分配一定的不变量,这样的分级,涉及中央分次除代数和合适的半双线性型上的自由模。

英文摘要:

The fine abelian group gradings on the simple classical Lie algebras (including D4) over algebraically closed fields of characteristic 0 are determined up to equivalence. This is achieved by assigning certain invariant to such gradings that involve central graded division algebras and suitable sesquilinear forms on free modules over them.
