Comment on: "Application of Exp-function method for (3+1)-dimensional nonlinear evolution equations" [Comput. Math. Appl. 56 (2008) 1451-1456]
We show that Boz and Bekir [A. Boz, A. Bekir, Application of Exp-function method for (3+1)dimensional nonlinear evolution equations, Comput. Math. Appl. 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. (C) 2011 Elsevier Ltd. All rights reserved.
