摘要

设h为复单李代数g中的正则半单元，设t为不定式。我们考虑了包含t乘以h的g的幂级数的Iwahori子代数的“变种”。这个变种允许秩等于g的秩的自由阿贝群的自由作用。我们描述了这个作用的一个基本定义域。

Remarks on Affine Springer Fibres

Let h be a regular semisimple element in a complex simple Lie algebra g. Let t be an indeterminate. We consider the "variety" of Iwahori subalgebras of g tensored with power series in t which contain t times h. This variety admits a free action of a free abelian group of rank equal to the rank of g. We describe a fundamental domain for this action.
