A basic question in symplectic geometry is to classify manifolds by symplectomorphisms. This question is widely open even for open submanifolds of the standard Cartesian spaces in general. We develop techniques in differential topology to show that some subsets can be removed or excised from a noncompact symplectic manifold without affecting its symplectic structure. We use incomplete Hamiltonian vector fields and examples include a properly embedded ray.
