Comment on: 'Application of Exp-function method for (3 + l)-dimensional nonlinear evolution equations' [Comput. Math. Appl. 56 (2008) 1451-1456]

摘要

We show that Boz and Bekir [A. Boz, A. Bekir. Application of Exp-function method for (3+1 )-dimensional nonlinear evolution equations, Comput. Math. Appi. 56 (2008) 1451-1456] obtained some incorrect solutions for the equations studied by means of the Exp-function method. We verify our assertion by direct substitution and pole order analysis. In addition, we provide the correct results using the same approach.
