Prolongation of regular-singular connections on punctured affine line over a Henselian ring abstract
Abstract:
We generalize Deligne’s equivalence between the categories of regular- singular connections on the formal punctured disk and on the punctured affine line to the case where the base is a strictly Henselian discrete valuation ring of equal characteristic 0. We also provide a weaker result when the base is higher dimensional.This is a joint work with João Pedro dos Santos, Pham Thanh Tâm, and Ðào Van Thinh
