Vector hyperbolic equations with higher symmetries
A. G. Meshkov Orel State University for Technology, Orel, Russia
Abstract:
We list eleven vector hyperbolic equations that have third-order symmetries with respect to both characteristics. This list exhausts the equations with at least one symmetry of a divergence form. We integrate four equations in the list explicitly, bring one to a linear form, and bring four more to nonlinear ordinary nonautonomous systems. We find the Bäcklund transformations for six equations.
Keywords:
hyperbolic equation, higher symmetry, integral, Bäcklund transformation, exact integrability.
