The Cauchy Problem for the Nonlinear Schrödinger Equation on a Compact Manifold

چکیده
We discuss the wellposedness theory of the Cauchy problem for the nonlinear Schrödinger equation on compact Riemannian manifolds. New dispersive estimates on the linear Schrödinger group are used to get global existence in the energy space on arbitrary surfaces and three-dimensional manifolds, generalizing earlier results by Bourgain on tori. On the other hand, on specific manifolds such as spheres, new instability phenomena are displayed, leading to some kind of illposednesss in higher dimensions.

The Schrödinger equation on a compact manifold : Strichartz estimates and applications
We prove Strichartz estimates with fractional loss of derivatives for the Schrödinger equation on any riemannian compact manifold. As a consequence we infer global existence results for the Cauchy problem of nonlinear Schrödinger equations on surfaces in the case of defocusing polynomial nonlinearities, and on three–manifolds in the case of quadratic nonlinearities. We also discuss the optimali...
متن کاملOn Strichartz’s Inequalities and the Nonlinear Schrödinger Equation on Irrational Tori
Strichartz’s inequalities and the Cauchy problem for the nonlinear Schrödinger equation are considerably less understood when the spatial domain is a compact manifold M , compared with the Euclidean situation M = R . In the latter case, at least the theory of Strichartz inequalities (i.e., moment inequalities for the linear evolution, of the form ‖eit φ‖Lpx,t ≤ C‖φ‖L2x ) is basically completely...
متن کاملAdomian Decomposition Method On Nonlinear Singular Cauchy Problem of Euler-Poisson- Darbuox equation
n this paper, we apply Picard’s Iteration Method followed by Adomian Decomposition Method to solve a nonlinear Singular Cauchy Problem of Euler- Poisson- Darboux Equation. The solution of the problem is much simplified and shorter to arriving at the solution as compared to the technique applied by Carroll and Showalter (1976)in the solution of Singular Cauchy Problem.
