The Structure of the Normalizers of Maximal Toruses in
Lie-Type Groups
摘要
Abstract
The main aim of the present article is to survey results on the structure of the normalizersof maximal toruses in Lie-type groups. In particular, we present results on splitting ofthe normalizer of a maximal torus and, in the case of exceptional groups, on the minimal order ofa lift in the corresponding normalizer for elements of the Weyl group.
