제목: Symplectic and contact topology of singularities

초록: For an isolated singularity, the intersection with a small sphere forms a smooth manifold, called the link of the singularity. It admits an additional geometric structure, called a contact structure, and this turns out to be a finer invariant of singularities than the smooth structure. In this talk, we briefly introduce results on relationships between symplectic and contact topology and singularity theory, in terms of the classification problem of symplectic manifolds with contact boundary.
