Notes:
A new integrable nonlinear partial differential equation (PDE) in 2+1 dimensions is derived starting from the Konopelchenko–Dubrovsky equation. We use an asymptotically exact reduction method based on Fourier expansion and spatio-temporal rescaling and obtain a new integrable Davey–Stewartson-type equation. In order to demonstrate the integrability of the new equation by the inverse scattering method, we apply the reduction technique to the Lax pair of the Konopelchenko–Dubrovsky equation and find the corresponding Lax pair of the new equation. The new equation reduces to the Davey–Stewartson or the nonlinear Schrodinger equation by appropriate limits. © 1999 American Institute of Physics.
