**Title: Symplectic Dynamics**

Abstract: This talk is about the emerging field of Symplectic Dynamics, which is a very successful combination of Symplectic Geometry/Topology and Dynamical Systems Theory. Although it is difficult to give a precise definition of this field, it is not difficult to give examples demonstrating how integrated ideas from both fields answer nontrivial questions. The modern theory of Dynamical Systems and the field of Symplectic Geometry emerged from Poincaré’s integrated viewpoint of Mathematics, but then developed independently. However, in the last twenty years these different mathematical streams started to merge, resulting in new viewpoints. This talk, aiming at a general mathematical audience, will describe this development and will mention some of the achievements and open problems.

**5:30-6PM Geometry Cafe, followed by Food & Beverage Hour

Geometry Cafe is a Q&A session with Professor Hofer in a casual setting.

**Biography**

Professor Helmut Hofer received his Ph.D. from the University of Zurich in 1981. He is currently a faculty member at the Institute for Advanced Study, Princeton. He received a Sloan Fellowship in 1987, and gave invited addresses at the ICM’s in Kyoto (1990) and Berlin (1998). He is a member of the National Academy of Sciences, the Academia Europaea, and the German Academy of Sciences Leopoldina. He works in symplectic geometry/topology, dynamical systems and partial differential equations.
