p-Adic Weight Spectral Sequences of Strictly Semi-stable Schemes over Formal Power Series Rings via Arithmetic D-modules
Abstract
Let k be a perfect field of characteristic p > 0. For a strictly semi-stable scheme over k[[t]], we construct the weight spectral sequence in p-adic cohomology using the theory of arithmetic D-modules, whose E1 terms are described by rigid cohomologies of irreducible components of the closed fiber and whose E∞ terms are conjecturally described by the (unipotent) nearby cycle of Lazda-P\'al's rigid cohomology over the bounded Robba ring. We also show its functoriality by pushforward and state the conjecture of its functoriality by pullback and dual.
