  Fumiharu Kato

  Professor Fumiharu Kato earned his Ph.D. in Science from Kyoto University in January 1997. Throughout his career, he has held positions at various universities, including Kyushu University, Kyoto University, Kumamoto University and Tokyo Institute of Technology. Specializing in algebraic and arithmetic geometry, specifically rigid geometry (non-Archimedean geometry), Professor Kato has contributed significantly to foundational research in these areas. He has a longstanding friendship with Professor Shinichi Mochizuki, the founder of the IUT theory, and together they witnessed the theory’s development through their private seminars over six years. Besides his academic pursuits, Professor Kato nurtures a love for music, with piano playing and choral singing being his hobbies. During his student time at Kyoto University, he even studied the Saito-style conducting method under a professional conductor. Professor Kato’s diverse interests and talents reflect his deep passion for both mathematics and music.
