Unique continuation along curves and hypersurfaces for second order anisotropic hyperbolic systems with real analytic coefficients
Jin Cheng, Ching-Lung Lin, Gen Nakamura · Proceedings of the American Mathematical Society · 2005
In this paper we prove the following kind of unique continuation property. That is, the zero on each geodesic of the solution in a real analytic hypersurface for second order anisotropic hyperbolic systems with real analytic coefficients can be continued along this curve.
