Twisted GKZ hypergeometric functions and relative cohomology

Algebraic Geometry 2023-02-17 v1

Abstract

We investigate the GKZ AA-hypergeometric D\mathscr{D}-modules, introduced by Gel'fand, Kapranov, and Zelevinskii, arising from cyclic covers of toric varieties and find its Riemann--Hilbert partner. This extends our earlier results in arXiv:1902.01536.
