Ruslan Leont'evich Stratonovich (Russian: Русла́н Лео́нтьевич Страто́нович) was a Russian physicist, engineer, and probabilist and one of the founders of the theory of .
Ruslan Stratonovich was born May 31, 1930 in Moscow. He studied from 1947 at the Moscow State University, specializing in there under P. I. Kuznetsov on radio physics (a Soviet term for oscillation physics - including noise - in the broadest sense, but especially in the electromagnetic spectrum). In 1953 he graduated and came into contact with the mathematician Andrey Kolmogorov. In 1956 he received his doctorate (theory of correlated random points apply to the calculation of electronic noise). In 1969 he became professor of physics at the Moscow State University.
Stratonovich invented a which serves as an alternative to the Itō calculus; the Stratonovich calculus is most natural when physical laws are being considered. The Stratonovich integral appears in his . Here, the Stratonovich integral is named after him (at the same time developed by Donald Fisk). He also solved the problem of optimal non-linear filtering based on his theory of conditional Markov processes, which was published in his papers in 1959 and 1960. The Kalman-Bucy (linear) filter (1961) is a special case of Stratonovich's filter.
The Hubbard-Stratonovich transformation in the theory of path integrals (or distribution functions of statistical mechanics) was introduced by him (and used by John Hubbard in solid state physics).
