dc.description.abstract | Perverse schobers are categorifications of perverse sheaves. In prior work we constructed a perverse schober on a partial compactification of the stringy Kahler moduli space (SKMS) associated by Halpern-Leistner and Sam to a quasi symmetric representation of a reductive group. When the group is a torus the SKMS corresponds to the complement of the GKZ discriminant locus (which is a hyperplane arrangement in the quasi-symmetric case shown by Kite). We show here that a suitable variation of the perverse schober we constructed provides a categorification of the associated GKZ hypergeometric system in the case of non resonant parameters. As an intermediate result we give a description of the monodromy of such "quasi-symmetric " GKZ hypergeometric systems. (C) 2022 Elsevier Inc. All rights reserved. | - |
