摘要
Let C be a complex projective smooth curve and W a symplectic vector bundle of rank 2n over C. The Lagrangian Quot scheme LQ(-e)(W) parameterizes subsheaves of rank n and degree -e which are isotropic with respect to the symplectic form. We prove that LQ(-e)(W) is irreducible and generically smooth of the expected dimension for all large e, and that a generic element is saturated and stable.
