On duality of certain GKZ hypergeometric systems
Lev Borisov, Zengrui Han, Chengxi Wang
We study a pair of conjectures on better behaved GKZ hypergeometric systems of PDEs inspired by Homological mirror symmetry for crepant resolutions of Gorenstein toric singularitie…

On strong exceptional collections of line bundles of maximal length on Fano toric Deligne-Mumford stacks
Lev Borisov, Chengxi Wang
We study strong exceptional collections of line bundles on Fano toric Deligne-Mumford stacks with rank of Picard group at most two. We prove that any strong…

On stringy Euler characteristics of Clifford non-commutative varieties
Lev Borisov, Chengxi Wang
It was shown by Kuznetsov that complete intersections of generic quadrics in are related by Homological Projective Duality to certain non-commutative (Clif…
