Dmitri Yafaev

Dmitri R. Yafaev (Дмитрий Рауэльевич Яфаев; 2 January 1948 – 16 June 2024) was a Russian-French mathematical physicist.

At the University of Leningrad (now renamed Saint Petersburg State University) Yafaev received his Russian Candidate degree (Ph.D.) in 1973 with thesis advisor Mikhail Birman and was a lecturer from 1973 to 1977. From 1977 to 1990 Yafaev was a researcher and senior researcher at the St. Petersburg Branch of the Steklov Institute of Mathematics. At the University of Nantes he was an associate professor from 1990 to 1992. From 1992 he was a full professor at the University of Rennes 1.

Yafaev's research deals with "spectral theory of differential operators; spectral properties of scattering matrices; long-range scattering theory; magnetic Hamiltonians". He is the author of three books and numerous articles. He was on the editorial boards of several journals, including Integral Equations and Operator Theory.

He was an invited speaker in 1998 of the International Congress of Mathematicians in Berlin and in 2003 at the 14th International Congress on Mathematical Physics in Lisbon.

Yafaev died on 16 June 2024, at the age of 76.
