Hanlon-Hicks-Lazarev resolution revisited
Lev Borisov, Zengrui Han
Hanlon, Hicks and Lazarev constructed resolutions of structure sheaves of toric substacks by certain line bundles on the ambient toric stacks. In this paper, we give a new and subs…

Central charges in local mirror symmetry via hypergeometric duality
Zengrui Han
We apply the better-behaved GKZ hypergeometric systems to study toric Calabi-Yau Deligne-Mumford stacks and their Hori-Vafa mirrors given by affine hypersurfaces in algebraic tori.…

Analytic continuation of better-behaved GKZ systems and Fourier-Mukai transforms
Zengrui Han
We study the relationship between solutions to better-behaved GKZ hypergeometric systems near different large radius limit points, and their geometric counterparts given by the …
