My CV (my page in researchmap)
I am a mathematician working in Osaka, Japan. My speciality is Algebraic Geometry, which is a study of shapes given by polynomial equations. My recent studies are about what might be called Arithmetic Singularities, that is, a study of relation between singularities of such shapes and the number theory.
Keywords of my works include:
singularities, jets and arcs, motivic and p-adic integration, the McKay correspondence, rational points, higher Semple-Nash blowups and F-blowups, wild quotient singularities, counting field extensions
I will co-organize the following one-day workshop with K. Aoyama and Y. Kaijima:
Osaka One-day Workshop on Arithmetic of Stacks and Coverings
University of Osaka, June 27, 2025
