Hidenori Fujiwara’s Biography

Hidenori Fujiwara was born in 1946 at Okayama in Japan. He was enrolled in Tokyo University in 1965 and then dropped out soon after. He failed right afterwards to go to the faculty of sciences and unwillingly oriented to the faculty of technology. Being interested in mathematics, he studied it by himself and was admitted in 1972 to the master course in mathematics of Tokyo University. His adviser, Professor Masahiko Saito asked him at the beginning of his career to study the text written in French by L. Pukanszky. It was his encounter with nilpotent Lie groups, representations and also with French language. 

   In 1977, he obtained the doctor degree at Tokyo University on holomorphically induced representations of exponential solvable Lie groups. At that time many people were working on harmonic analysis for solvable homogeneous spaces and there were many active groups in the world; two of them were in Paris around  J. Dixmier, M. Duflo, M. Vergne and in Bielefeld around H. Leptin. 

     In 1976, he was employed as an assistant in Kyushu University and moved to Kinki University for a full Professor position in 1987. 

    Being a student of Professor Jean Ludwig, this gave me the opportunity to meet him in Metz University several times and I learnt a lot from some discussions with him, which I enjoyed very much. He was one of the evaluators of my Phd thesis defended in June 1995.
  
    In 2005, he got the “Analysis prize” from the Mathematical society of Japan for his pioneer works solving the so called the commutativity conjecture for induced monomial representations of connected and simply connected nilpotent Lie groups. The upshot followed from a series of papers published with Gerard Lion, Bernard Magneron, Salah Mehdi, Jean Ludwig and myself. 

    Throughout, I was interested with him to solve the parallel Conjecture in the context of restricted representations for nilpotent Lie groups and published the result in 2004.

    He supervised the scientific works of Junko Inoue, who is one of the active researchers in the field of non-commutative harmonic analysis. 

Being one of the prominent researchers in his field, he continues to be interested in orbit Method for solvable Lie groups, where many interesting problems remain to be solved.
