Paola Cellini, Pierluigi Moseneder Frajria, Paolo Papi, Marco Pasquali

摘要:

设g=g_0+g_1是Z_2-分次李代数.本文研究了g_1中相对稳定的交换子代数的偏序集。g_0的Borel子代数。特别地,我们找到了极大元的自然参数化和它们的维数公式。我们恢复作为特殊情况的几个结果Kostant,Panyushev,苏特。

英文摘要:

Let g=g_0+g_1 be a Z_2-graded Lie algebra. We study the posets of abelian subalgebras of g_1 which are stable w.r.t. a Borel subalgebra of g_0. In particular, we find out a natural parametrization of maximal elements and dimension formulas for them. We recover as special cases several results of Kostant, Panyushev, Suter.
