完全可约和可分域扩张
Complete reducibility and separable field extensions
摘要:
设G是连通的约化线性代数群.本文的目的是解决J-P. Serre关于他的G-完全归约概念在可分域扩张下的行为的一个问题。我们的部分证明依赖于最近建立的山雀中心猜想的球形建设的约化群G。
英文摘要:
Let G be a connected reductive linear algebraic group. The aim of this note is to settle a question of J-P. Serre concerning the behaviour of his notion of G-complete reducibility under separable field extensions. Part of our proof relies on the recently established Tits Centre Conjecture for the spherical building of the reductive group G.
