Comment on: "New exact solutions for the Kawahara equation using Exp-function method"
arXiv:1004.1049
Abstract
Exact solutions of the Kawahara equation by Assas [L.M.B. Assas, J. Com. Appl. Math. 233 (2009) 97--102] are analyzed. It is shown that all solutions do not satisfy the Kawahara equation and consequently all nontrivial solutions by Assas are wrong.
