MY WORKSI study ARITHMETIC GEOMETRY. Especially, I am mainly interested in: $p$-adic Hodge theory and related topics ($(phi,Gamma)$-modules, $p$-adic differential equations...), Iwasawa theory and Bloch-Kato's Tamagawa number conjecture, multiple zeta values, fundamental groups, and mixed Tate motives, Shimura varieties, Drinfel'd modular varieties, moduli of shutkas, and ($p$-adic) Langlands corresponden
