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. 

Key words: standard Levi-form, induced module, coinduced module, Ext-groups
