Abstract:   The category of homogeneous vector bundles on a flag manifold X=G/P of ADE-type is equivalent to the category of representations of a certain quiver Q_X with relations. This equivalence was found in some cases by Bondal, Kapranov and Hille. In the particular case of Hermitian symmetric varieties, Ottaviani and Rubei used this equivalence as a tool to compute the cohomology of homogeneous vector bundles, thus generalizing the well-known Borel-Weil-Bott Theorem to not necessarily irreducible bundles. I will show results holding in the general case.
