Vanishing theorem for the cohomology of line bundles on Bott-Samelson varieties
arXiv:0811.4263
Abstract
We use the toric degeneration of Bott-Samelson varieties and the description of cohomolgy of line bundles on toric varieties to deduce vanishings results for the cohomology of lines bundles on Bott-Samelson varieties.
