WebStill working in characteristic 0, he derived a "very simple" proof of the theorems of Borel-Weil and Bott, then showed how to derive the Weyl character formula and implement it effectively in this same framework. 4) As pointed out by Aakumadule, Kumar's proof of the old PRV conjecture on tensor products of irreducibles (predicting certain ... WebThis is modeled on the following rewriting of the Borel-Weil-Bott theorem. Let P G⊂ be a parabolic subgroup, E an irrep of G, F one of P. The group cohomology H P ∗( )E F⊗ of P, with coef-ficients in E F⊗ , is determined as follows. If Ä is the sheaf of sections of the algebraic vector

WebF is equivalent to the Borel-Weil-Bott theorem (‘‘BWB’’) for the flag variety G=P. The argument (due to Bott) is usually given in Lie algebra terms, so let me rephrase it. If F is the sheaf of sections of the algebraic vector bundle G P F over G=P, one has a spectral sequence of ‘‘cohomological descent from G to G=P’’, with Ep ...
