N-soliton solutions for a (3+1)-dimensional nonlinear evolution equation

Abstract Via Hirota bilinear method and perturbation technique, a more general N-soliton solution with a parameter p for a (3+1)-dimensional nonlinear evolution equation is obtained. And two N-soliton solutions in terms of Wronskian determinant are also presented in the case of p = 1 and p = 3.
