Takehiko Yasuda

I am a mathematician working for Department of Mathematics, Osaka University as an associate professor. My research area has been the algebraic geometry, the geometry studying shapes or spaces given by polynomial equations; namely, algebraic varieties in technical terms. In particular, singularities of such shapes have been my primary interests. In last years, I mainly worked on problems where the number theory and the singularity theory interplay. Now my interest inclines toward the Diophantine geometry.  


  • singularities of algebraic varieties
  • 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
