Outline of Final Research Achievements

We studied p-adic geometry of Shimura varieties. In particular, we construct potentially good reduction locus, where motives don't degenerate, as an open subspace of the adic space associated to a Shimura variety over p-adic field. Further, we studied it's cohomology.
We studied also on the Kramer-Tunnel conjecture, which describe the epsilon factor of an elliptic curve over an local field by rational points of the elliptic curve. The conjecture was open in the characteristic two case. We showed the conjecture by reducing it to the characteristic zero case.
