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 (nonArchimedean analytic geometry and formal geometry) and arithmetic geometry.
