Exceptional collections for Grassmannians of isotropic lines

Algebraic Geometry 2014-02-26 v2

Abstract

We construct a full exceptional collection of vector bundles in the derived category of coherent sheaves on the Grassmannian of isotropic two-dimensional subspaces in a symplectic vector space of dimension 2n2n and in the derived category of coherent sheaves on the Grassmannian of isotropic two-dimensional subspaces in an orthogonal vector space of dimension 2n+12n + 1 for all nn.
