The Gauss-Manin system of an ICIS

Algebraic Geometry 2025-06-26 v1

Abstract

For an isolated complete intersection singularity (ICIS), we define and study its Gauss-Manin system and its associated Hodge filtration. We show the relation between the Hodge filtration and a generalized Brieskorn lattice and study conditions for the existence of a microlocal structure. Using these ideas, we relate the residue on the saturated Brieskorn lattice with a bb-function introduced by Torrelli.
