Counting sheaves on Calabi-Yau 4-folds Oh, Jeongseok
Description
We define a localised Euler class for isotropic sections, and isotropic cones, in \(SO(N)\) bundles. We use this to give an algebraic definition of Borisov-Joyce's sheaf counting invariants on Calabi-Yau 4-folds. When a torus acts, we prove a localisation result. This talk is based on the joint work with R. P. Thomas.
