On the solutions and conservation laws of a two-dimensional Korteweg de Vries model: Multiple exp-function method

Abstract

AbstractUnder investigation in this paper is a two-dimensional Korteweg de Vries model, which is a spacial extension of the Korteweg de Vries model. An infinite number of nonlocal conservation laws are given which indicate the integrability of this model. Exact soliton solutions are then respectively derived by means of the multiple exp-function method.
