Yakov G. Sinai

For work revolutionizing the study of dynamical systems and influenced statistical mechanics, probability theory and statistical physics

Yakov G. Sinai, professor of mathematics at Princeton University since 1993, is internationally regarded as a pioneer in the field of dynamical systems. His work has revolutionized the study of dynamical systems and influenced statistical mechanics, probability theory and statistical physics.

Sinai's work deals with measuring dynamical systems, or systems that change over time, such as weather, the motion of planets and economic systems. These systems can be accurately measured in the short term (short term being relative to the issue at hand); but when analyzed in the long term, the systems are difficult to understand and predict. Sinai was the first to come up with a mathematical foundation for determining the number that defines the complexity of a given dynamical system. His mathematical system is called Kolmogorov-Sinai entropy.

Sinai received his bachelor's, master's and doctorate degrees from Moscow State University. He also held several positions with Moscow State University, including researcher with the Laboratory of Probabilistic and Statistical Methods (1971-present) and professor of mathematics (1971-93). In addition, Sinai has served as a senior researcher at the Landau Institute of Theoretical Physics, Academy of Sciences.

Sinai's contributions have been recognized by numerous organizations. He has been the recipient of several awards and honors, including memberships in the Russian, U.S. and Hungarian Academies of Science, and an honorary membership in the London Mathematics Society. Other awards include the Thomas Jones Professor of Princeton University, Wolfe Foundation Prize in Mathematics, Doctor Honoris Causa of Warsaw University, Markov Prize, Heineman Prize and Boltzman Gold Medal.

Sinai has been an invited speaker at several important international conferences. He has spoken four times at the International Congress of Mathematics and has delivered lectures at Harvard University and the Hebrew University of Jerusalem.
