Cohomology of Line Bundles: A Computational Algorithm
arXiv:1003.5217 · doi:10.1063/1.3501132
Abstract
We present an algorithm for computing line bundle valued cohomology classes over toric varieties. This is the basic starting point for computing massless modes in both heterotic and Type IIB/F-theory compactifications, where the manifolds of interest are complete intersections of hypersurfaces in toric varieties supporting additional vector bundles.
