Abstract

We observe that the form of the Kadomstev–Petviashvili equation studied by Yu (2011) [S. Yu, N-soliton solutions of the KP equation by Exp-function method, Appl. Math. Comput. (2011) doi:10.1016/j.amc.2010.12.095] is incorrect. We claim that the N-soliton solutions obtained by means of the basic Exp-function method and some of its known generalizations do not satisfy the equation considered. We emphasize that Yu’s results (except only one) cannot be solutions of the correct form of the Kadomstev–Petviashvili equation. In addition, we provide some correct results using the same approach.
