模李代数的Ext-转移(英文)

Ext-transfer for modular Lie algebras

令G为素特征代数闭域上简约连通的代数群,g是G的李代数.本文研究,当p特征x具有标准Levi型时,g表示的Ext上同调群.得到了g模到其Levi子代数的模上的Ext转移.

Let G be a connected reductive algebraic group over an algebraically closed field k of prime characteristic p and g =Lie（G）.This paper studied the Ext-groups of g with a p-character x of standard Levi form.An Ext-transfer result from g-modules to the modules of its Levi subalgebras was obtained.
