Ovidiu Calin and Vittorio Mangione: Some hyperbolic PDE's from a geometric point of view, p. 147-158

Abstract:

We prove the uniqueness for the solutions of some hyperbolic boundary problems by means of conservation property of the energy-momentum tensor associated with a Lagrangian.

Key Words: null cone, wave operator, Lorentz space, energy-momentum tensor, dominant energy condition.
