Ludvig Faddeev
Russian mathematician and physicist (1934–2017)
Ludvig Dmitrievich Faddeev (also Ludwig Dmitriyevich; Russian: Лю́двиг Дми́триевич Фадде́ев; 23 March 1934 – 26 February 2017) 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 (with Victor Popov). 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.
Biography
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, Vera Faddeeva, 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".
The public source identifies “Ludvig Faddeev” as russian mathematician and physicist (1934–2017). This brief keeps that definition visible, then builds a research path around Ludvig, Faddeev and Russian.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Ludvig Faddeev”, the useful work is to connect “russian mathematician and physicist (1934–2017)” to the records capable of establishing context and consequence.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q1030228. VIAF identifies the subject as 7476034. The Library of Congress control number is n80123047. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1934, 2017 and 1956.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
