New exact solutions of a new (2+1)-dimensional integrable system

In this Letter, a new (2+1)-dimensional integrable system is solved by using the modified Jacobi elliptic function expansion method. As a consequence, abundant families of Jacobi elliptic function solutions are obtained. When the modulus m→1 and m→0, those periodic solutions degenerate as the corresponding solitary wave solutions, shock wave solutions or trigonometric function solutions
