Research Field : Algebraic fibrations of curves

Research Summary : I study classification problems on algebraic varieties by fundamental invariants such as Kodaira dimensions and fundamental groups by the following methods: (1) separable quotients and inseparable quotients; (2) rigid analytic geometry (non-Archimedean analytic geometry and formal geometry) and arithmetic geometry.
