Injectivity of Generalized Wronski Maps Academic Article uri icon


  • © Canadian Mathematical Society 2017. We study linear projections on Plücker space whose restriction to the Grassmannian is a non-trivial branched cover. When an automorphism of the Grassmannian preserves the fibers, we show that the Grassmannian is necessarily of m-dimensional linear subspaces in a symplectic vector space of dimension 2m, and the linear map is the Lagrangian involution. The Wronski map for a self-adjoint linear differential operator and the pole placement map for symmetric linear systems are natural examples.
