Holomorphic Curves in Symplectic Topology
Professor Yakov Eliashberg
As it was discovered in the early fifties symplectic structures and symplectic transformations have amazing rigidity properties. For example, the group of symplectic transformations is C0-closed in the group of volume preserving transformations. The group of symplectomorphisms also admits a bi-invariant metric, which is highly unusual for non-compact infinite-dimensional groups. The theory of holomorphic curves in symplectic manifolds which was introduced by M. Gromov serves as a major tool for handling these questions, as well as other problems in Symplectic Topology. In the course we will discuss the main notions and problems of Symplectic topology and will explain the role played by the theory of holomorpic curves. We will also discuss the relevant algebraic formalism, called Symplectic Field Theory.
