About Ludvig Faddeev
Ludvig Dmitrievich Faddeev was a Soviet and Russian mathematical physicist. He is known for the discovery of the Faddeev equations in 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 of the 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. His mother, Vera Faddeeva, was known for her work in numerical linear algebra. In 1988 he founded the Euler International Mathematical Institute, now a department of PDMI RAS. He was awarded the Henri Poincaré Prize in 2006 and the Shaw Prize in mathematical sciences in 2008.
