Accademic Interests (Not Necessarily Mathematical)

  • Number Theory: This is supposed to be my major area of interest. I'm particularly interested in the theory of automorphic forms, Langlands program etc.
  • Arithmetic Algebraic Geometry: This is, as far as I understand, some mixture of number theory and algebraic geometry.
  • Mathematical Logic: Originally, I started my mathematical career as a logician. Among various branches of logic, I find model theory particularly interesting.
  • Wittgenstein: This guy is the one who has impressed me most throughout my philosophical career.
  • History of Japan: I'm especially interested in Japan's history from the mid 19th century to 1945. This is the most exciting period throughout the history of Japan.
