Yakov B. Pesin

Yakov Pesin is Distinguished Professor of Mathematics and the director of Anatole Katok Center for Dynamical Systems and Geometry at The Pennsylvania State University. Pesin’s primary areas of research are the theory of dynamical systems with an emphasis on smooth ergodic theory, dimension theory in dynamical systems, and Riemannian geometry. He is also interested in mathematical and statistical physics, and has solved several mathematical conjectures, including the “Entropy conjecture” in smooth ergodic theory and the "Eckmann-Ruelle conjecture” in dimension theory. He is the originator of the "Pesin theory” of non-uniformly hyperbolic dynamical systems, and author of Dimension Theory in Dynamical Systems. He has made foundation contributions to the theory of coupled map lattices, also known as dynamical networks, which has become important for numerous applications in physics and biology. Pesin is a Fellow of the American Mathematical Society and a foreign member of the Academy of Europe. He holds a Ph.D. from Moscow State University.
