Laptev, A.; Safarov, Yu. G. Global solution of the wave equation. (English) Zbl 0719.58041 Journ. Équ. Dériv. Partielles, St.-Jean-De-Monts 1990, Exp. No. 18, 9 p. (1990). The main result is that it is possible to parametrize the family of Lagrangian manifolds associated with the Schrödinger operator on a Riemannian manifold globally with a complex-valued generating function.
