Born in Moscow in 1935, Yakov Sinai was educated at Moscow State
University and was a researcher there in the 1960s and a professor from
1971 to 1993, when he went to Princeton University as professor of
mathematics. Since 1971 he has also held the position of senior
researcher at the Landau Institute of Theoretical Physics.
In 1997, Professor Sinai shared the prestigious Wolf Prize in
Mathematics with Joseph Keller of Stanford University, and was cited by
the Wolf Foundation for "his fundamental contributions to mathematically
rigorous methods in statistical mechanics and the ergodic theory of
dynamical systems and their applications in physics". Among his previous
awards are the 1989 Heineman Prize and the 1992 Dirac Medal.
Professor Sinai's work deals with measuring complex systems that change
over time, such as the weather and economic systems. He was the first to
develop a mathematical description of the complexity of changing,
chaotic systems, creating an approach now called Kolmogorov-Sinai
entropy. This work gives mathematicians a critical tool for solving the
complex equations that describe such systems.
Professor Sinai has published the following book with World Scientific:
