Higher-Order Equations of the KdV Type are Integrable
We show that a nonlinear equation that represents third-order approximation of long wavelength, small amplitude waves of inviscid and incompressible fluids is integrable for a particular choice of its parameters, since in this case it is equivalent with an integrable equation which has recently appe...

| Summary: | We show that a nonlinear equation that represents third-order
approximation of long wavelength, small amplitude waves of inviscid and incompressible
fluids is integrable for a particular choice of its parameters, since in this
case it is equivalent with an integrable equation which has recently appeared in
the literature. We also discuss the integrability of both second- and third-order
approximations of additional cases. |
