  • Hosung Kim, The Space of Rational Curves on a General Hypersurface of Projective Space

    B266 IBS, Korea, Republic of
    Complex Geometry Seminar

         Speaker Hosung Kim IBS, Center for Complex Geometry In 1979, the work of Mori had brought out the importance of the study of rational curves in higher-dimensional geometry. In 1990s, applying Mori's bend-and-break method, Campana and Kollar-Miyaoka-Mori proved that any Fano manifold is rationally connected. Since then the family of raional curves on …

  • Hosung Kim, Lagrangian Fibration Structure on the Cotangent Bundle of a Del Pezzo Surface of Degree 4

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

         Speaker Hosung Kim IBS CCG (This is a part of Seminars on Algebraic Surfaces and Related Topics.) The cotangent bundle of a complex projective manifold carries a natural holomorphic symplectic 2-form. The existence of a natural Lagrangian fibration structure of these non-compact complex manifolds has not been studied very much. In this talk, …
