Description
Abstract: The quantum sheaf cohomology (QSC) is a deformation of the classical sheaf cohomology ring of a holomorphic vector bundle $E$ and is a generalization of quantum cohomology. We review the version of QSC for toric varieties that corresponds to the description of the geometric phase of A/2 twisted, 2d (0,2) GLSMs. We then present a Sheaf COhomology REstriction (SCORE) formula, which transfers the computation of classical sheaf cohomology (and correlators) for toric complete intersections to the ambient toric variety. After that we discuss some work in progress on quantum corrections.
