New multiple soliton-like solutions to the generalized (2 + 1)-dimensional KP equation

摘要

A new generalized tanh function method is used for constructing exact travelling wave solutions of nonlinear partial differential equations (PDEs) in a unified way. The main idea of this method is to take full advantage of the Riccati equation which has more new solutions. More new multiple soliton-like solutions are obtained for the the generalized (2 + 1)-dimensional KP equation.
