Positivity in the Cohomology of Flag Bundles
Graham deduces this from a more general result about varieties with finitely many unipotent orbits, which is proved using induction and a calculation in the rank-one case. The goal of this note is to give a short, geometric proof of Graham’s positivity theorem, based on a transversality argument. Here I only discuss type A, but other types work as well. (For a type-uniform version, a change of ...
متن کاملThe cohomology of line bundles on the three dimensional flag variety
The purpose of this paper is to give a recursive description of the characters of the cohomology of the line bundles on the three dimensional flag variety over an algebraically closed field k of characteristic p > 0. In fact our recursive procedure also involves certain rank 2 bundles and we determine the characters of the cohomology of these bundles at the same time. The paper may be regarded ...
متن کاملPositivity in the cohomology of flag bundles (after Graham)
Graham deduces this from a more general result about varieties with finitely many unipotent orbits, which is proved using induction and a calculation in the rank-one case. (In fact, A. Knutson points out that Graham’s proof yields a stronger result: as a polynomial in all the negative roots, cuv is a nonnegative combination of squarefree monomials.) The goal of this note is to give a short, geo...
متن کاملOn the Principal Bundles over a Flag Manifold
Let P be a parabolic subgroup of a semisimple simply connected linear algebraic group G over C and ρ an irreducible homomorphism from P to a complex reductive group H . We show that the associated principal H –bundle over G/P , associated for ρ to the principal P –bundle defined by the quotient map G −→ G/P , is stable. We describe the Harder–Narasimhan reduction of the G–bundle over G/P obtain...
متن کاملStructure of Cohomology of Line Bundles on G/B for Semisimple Groups Short running title: Cohomology of Line Bundles
Let G be a connected and simply connected semisimple algebraic group over an algebraically closed field k of characteristic p > 0, T a maximal torus of G and B a Borel subgroup containing T . Each weight in X(T ) determines a line bundle on the flag varietyG/B. It turns out that cohomology of the line bundle is isomorphic to the derived functor of the induction functors from the category of B-m...
