Morse-Bott functions from complex structures
Algebraic Geometry Seminar
Speaker Hyunmoon Kim Ewha Womans University We present a quadratic Morse-Bott function on the real Grassmannian of a symplectic vector space from a compatible linear complex structure. Its stable manifolds generalize the Lagrangian, symplectic, isotropic, and coisotropic Grassmannians to include the Grassmannians of linear subspaces that are neither isotropic, coisotropic, nor symplectic. The …
