Biography

The son of mathematicians, Corresponding member of the USSR Academy of Sciences Dmitry Faddeev (1907-1989) and Vera Faddeeva (nee Zamyatina, 1906–1983).

He finished the 155th boys school located in Smolninskiy district of Leningrad. Now it’s known as 155th gymnasium in the Central District of St. Petersburg. Faddeev attended the Faculty of Physics at Leningrad University, receiving his undergraduate degree in 1956. His doctoral work on scattering theory was completed in 1959 under the direction of Olga Ladyzhenskaya and Vladimir Fock. Candidate of Physical and Mathematical Sciences (1959); his thesis was “The properties of the S-matrix for scattering on local potential.” Doctor of Physical and Mathematical Sciences (1963), defended his thesis on the research results in the field of quantum scattering theory for the three-particle system. His doctoral thesis made the basis of a new scientific field in quantum physics. He founded the world-famous mathematical physics research school.

Professor of the Leningrad (St. Petersburg) State University (1967). A fellow member (academician) of the USSR Academy of Sciences (1976).

He worked at the Leningrad Department of the Mathematical Institute of the USSR first as a junior, then as a senior research officer, and after that was the head of the Mathematical Problems of Physics Laboratory. In the 1960s he prelected to the students of the Faculty of Mathematics and Mechanics upon quantum mechanics. Faddeev was the head of the St. Petersburg Department of Steklov Institute of Mathematics, Russian Academy of Sciences (PDMI RAS) from 1976 to 2000. He founded the Euler International Mathematical Institute, now a department of PDMI RAS, in 1988–1992. He held a position of the vice-president of the International Mathematical Union in 1983-1986, and in 1987-1990 became its President. At the same time, he headed the Higher Mathematics and Mathematical Physics Department of the Physical Faculty in Leningrad (St. Petersburg) State University (until 2001), hereafter was a professor of this Department. Ludvig Faddeev is a member of the Presidium of RAS and the St. Petersburg Scientific Centre of RAS. Also, he is an Academician-Secretary of the Department of Mathematical Sciences of RAS. He was the chairman of the Commission for medals and named prizes awarded by the Russian Academy of Sciences till 2016. He is a chief editor of the Functional Analysis and its Applications. He also was an editor-in-chief of the Nature magazine and a part of the first editorial board of the Theoretical and Mathematical Physics magazine. He is a member of editorial boards of the “Journal of Mathematical Physics”, the “Letters in Mathematical Physics”, the “Journal of Functional Analysis”, the “Reviews in Mathematical Physics”, the “Annals of Physics” and others.

Ludvig Faddeev said his teachers were Vladimir Fock and Olga Ladyzhenskaya (from the speech at the awarding of the Russian Federation State Prize in 2004).

Married to Anna Veselova, a theoretical physicist, has two daughters (Elena, a mathematician, and Maria, a theoretical physicist), four grandchildren and four great-grandchildren.


Scientific research

He has made a fundamental contribution to the solution of the three-body problem in quantum mechanics (Faddeev equations); the inverse scattering problem for the Schrödinger equation in three-dimensional case;, in the quantization of non-Abelian gauge fields by the path-integral (Faddeev-Popov ghosts, together with Victor Popov); the creation of the quantum theory of solitons and quantum inverse scattering method in the development of the theory of quantum groups. He has published five books and over 200 scientific papers. At the 23th International Conference on the quantum theory of several particles on August 11, 2016, it was decided to establish the International Ludvig Faddeev medal.
