Yakov Grigorevich Sinai ( _ru. Яков Григорьевич Синай; born September 21 1935) is one of the most Fact|date=August 2008 influential mathematicians of the twentieth century. He obtained numerous groundbreaking results in the theory of dynamical systems, in Mathematical Physics and in Probability theory. Especially his ingenious insights and pioneering works practically shaped the modern Metric Theory of Dynamical Systems (also often called after Kolmogorov the theory of Stochasticity of Dynamical Systems). Sinai was the major architect of the most bridges connecting the world of Deterministic (Dynamical) systems with the world of Probabilistic (Stochastic) systems.

Biography

Sinai was born in Moscow, USSR (now Russia) in a Jewish family that played a prominent role in Russia's scientific and cultural life since the nineteenth century. His grandfather, Veniamin Kagan, was one of the most famous Russian geometers, and Sinai's parents were prominent researchers in the medical and biological sciences.

Yakov Sinai received his Ph.D. from Moscow State University in 1960; his advisor was Andrey Kolmogorov. In 1971 he became a Professor at Moscow State University and a senior researcher at the Landau Institute of Theoretical Physics. Since 1993 he has been a Professor of Mathematics at Princeton University.

Sinai is a member of the United States National Academy of Sciences, Russian Academy of Sciences and others. Among the honors he has been awarded are the Boltzmann Medal (1986), Dirac Medal (1992), Dannie Heineman Prize for Mathematical Physics (1989), Nemmers Prize (2002), and the Wolf Prize in Mathematics (1997).

Sinai is one of a handful mathematicians who are highly respected by the Physics Community, where, as well as in mathematics, Kolmogorov-Sinai entropy, Sinai's billiards, Sinai's random walk, Sinai-Ruelle-Bowen measures, Pirogov-Sinai theory, etc, are uniformly considered to be the basic notions that shaped an understanding and intuition about many fundamental physical phenomena.

Sinai created a big and influential scientific school. Among his students are the members of some leading Academies and awardees of some the most prestigious prizes in mathematics. His innovative, highly original and creative style penetrates not only his papers and lectures, but also his numerous books where, even in the textbooks, the classical subjects like e.g. Probability Theory, there are always new chapters extending traditional views on the borders and content of the area.
