On Hypergeometric Duality Conjecture | Lev Borisov
; Zengrui Han
; | Date: |
3 Jan 2023 | Abstract: | We give an explicit formula for the duality, previously conjectured by Horja
and Borisov, of two systems of GKZ hypergeometric PDEs. We prove that in the
appropriate limit this duality can be identified with the inverse of the Euler
characteristics pairing on cohomology of certain toric Deligne-Mumford stacks,
by way of $Gamma$-series cohomology valued solutions to the equations. | Source: | arXiv, 2301.01374 | Services: | Forum | Review | PDF | Favorites |
