Abstract

We construct a K-theory version of Bhatt-Morrow-Scholze's Breuil-Kisin cohomology theory for \sOK\sO_K-linear idempotent-complete, small smooth proper stable infinity-categories, where KK is a discretely valued extension of \Qp\Q_p with perfect residue field. As a corollary, under the assumption that K(1)K(1)-local K theory satisfies the K\"unneth formula for \sOK\sO_K-linear idempotent-complete, small smooth proper stable \infty-categories, we prove a comparison theorem between K(1)K(1)-local K theory of the generic fiber and topological cyclic periodic homology theory of the special fiber with \Bcry\Bcry-coefficients, and pp-adic Galois representations of K(1)K(1)-local K theory for \sOK\sO_K-linear idempotent-complete, small smooth proper stable \infty-categories are semi-stable. We also provide an alternative K-theoretical proof of the semi-stability of p-adic Galois representations of the p-adic \'etale cohomology group of smooth proper varieties over KK with good reduction. is a short, This is a short preliminary version of the work that was later expanded in 2309.13654.
