Abstract

We present a complete list of nonlinear one-field hyperbolic equations with integrable third-order x and y symmetries. The list includes both equations of the sine-Gordon type and equations linearizable by differential substitutions.

Keywords

higher symmetry sine-Gordon type equation Liouville-type equation
