Solving the (2 + 1)-dimensional higher order Broer–Kaup system via a transformation and tanh-function method

In this paper, the (2 + 1)-dimensional higher order Broer–Kaup system is reduced to a simple nonlinear partial differential equation by a transformation, and utilizing tanh-function method we obtain many new exact solutions for the (2 + 1)-dimensional higher order Broer–Kaup system.
