PROLONGATION OF REGULAR-SINGULAR CONNECTIONS ON PUNCTURED AFFINE LINE OVER A HENSELIAN RING
Résumé
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.
