Energy splitting for solutions of multi-dimensional isotropic symmetric hyperbolic systems
Energy splitting for solutions of multi-dimensional isotropic symmetric hyperbolic systems
This note, submitted in honor of Walter Strauss’ 70th birthday, offers a new look at the elegant paper by Costa and Strauss entitled Energy Splitting, [3]. In it, they studied finite energy solutions to linear, constant coefficient, isotropic, symmetric hyperbolic systems. They showed that solutions separate, in L2, into a …
