具有简单Einstein导子的Einstein解流形

Einstein solvmanifolds with a simple Einstein derivation

Y. Nikolayevsky

摘要:

一个具有爱因斯坦左不变度量的可解李群的结构在某种意义上完全由它的李代数的零根决定。给出了一个易于检验的幂零代数是Einstein导子具有单特征值的Einstein幂零根的充要条件.作为应用,我们对丝状Einstein零根进行了分类(模丝状分次李代数的已知分类结果).

英文摘要:

The structure of a solvable Lie groups admitting an Einstein left-invariant metric is, in a sense, completely determined by the nilradical of its Lie algebra. We give an easy-to-check necessary and sufficient condition for a nilpotent algebra to be an Einstein nilradical whose Einstein derivation has simple eigenvalues. As an application, we classify filiform Einstein nilradicals (modulo known classification results on filiform graded Lie algebras).
