  • Yoosik Kim, Disk Counting via GIT Quotients

    B236-1 IBS, Korea, Republic of
    Algebraic Geometry Seminar

        Speaker Yoosik Kim Pusan National University According to the Kempf–Ness theorem, the GIT quotient is equivalent to the symplectic reduction. Using this correspondence, we explain how to relate the counting of holomorphic disks between a symplectic manifold equipped with a Hamiltonian group action and its symplectic reduction. As an application, we derive the
