Some hyperbolic PDE’s from a geometric point of view. (English) Zbl 1120.35310

Bull. Math. Soc. Sci. Math. Roum., Nouv. Sér. 47(95), No. 3-4, 147-157 (2004).

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