Ludvig Dmitrievich Faddeev - Biography#

Ludvig Dmitrievich Faddeev(also Ludwig Dmitriyevich; Лю́двиг Дми́триевич Фадде́ев; born March 23, 1934) is a Soviet and Russian theoretical physicist and mathematician. He is famous for the discovery of the Faddeev equations in the theory of the quantum mechanical three-body problem+ and for the development of path integral methods in the quantization of non-abelian gauge field theories, including the introduction (with Victor Popov) of Faddeev–Popov ghosts. He led the Leningrad School, in which he along with many of his students developed the quantum inverse scattering method for studying quantum integrable systems in one space and one time dimension. This work led to the invention of quantum groups by Drinfeld and Jimbo.

Faddeev was born in Leningrad to a family of mathematicians. His father, Dmitry Faddeev, was a well known algebraist, professor of Leningrad University and member of the Russian Academy of Sciences. His mother was known for her work in numerical linear algebra. Faddeev attended Leningrad University, receiving his undergraduate degree in 1956. He enrolled in physics, rather than mathematics, "to be independent of his father". Nevertheless, he received a solid education in mathematics as well "due to the influence of V. A. Fock and V. I. Smirnov". His doctoral work, on scattering theory, was completed in 1959 under the direction of Olga Ladyzhenskaya.

From 1976 to 2000, Faddeev was head of the St. Petersburg Department of Steklov Institute of Mathematics of Russian Academy of Sciences (PDMI RAS). In 1988 he founded the Euler International Mathematical Institute, now a department of PDMI RAS.

Faddeev has been a member of the Russian Academy of Sciences since 1976, and is a member of a number of foreign academies, including the U. S. National Academy of Sciences, the French Academy of Sciences, and the Royal Society. He received numerous honors including USSR State Prize (1971), Dannie Heineman Prize (1975), Dirac Prize (1990), Max Planck Medal (1996), Demidov Prize (2002 - "For outstanding contribution to the development of mathematics, quantum mechanics, string theory and solitons") and the State Prize of the Russian Federation (1995, 2004). He is a former president of the International Mathematical Union (1986–1990). He was awarded the Henri Poincaré Prize in 2006 and the Shaw Prize in mathematical sciences in 2008. Also the Karpinsky International Prize and the Max Planck Medal (German Physical Society).
