摘要: 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。Abstract: 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 of standard Levi form. An Ext-transfer result from g-modules to the modules of its Levi subalgebras was obtained.
