设E是正特征代数闭域k上的有限维线性空间,G=GL(E),P是G的抛物子群,使得G/P是k上的射影空间.设G1是G的Frobenius核,T是P的极大环面,我们将确定由1维P-模诱导的所有G1 P-模的G1 T-结构.特别是,它们都是无多重性和唯一性的。
Let E be a finite dimensional linear space over an algebraically closed field k of positive characteristic, G=GL(E), and P a parabolic subgroup of G such that G/P is a projective space over k. Let G1be the Frobenius kernel of G and T a maximal torus of P. We will determine the G1T-structure on all G1P-modules induced from 1-dimensional P-modules. They are, in particular, all multiplicity-free and uniserial.
