Comment on: Persistence of travelling wave for a coupled nonlinear wave system, Applied Mathematics and Computation 191 (2) (2007) 347–352

摘要

We comment on an error made in a recently published paper [Junliang Lu et al., Applied Mathematics and Computation 191 (2) (2007) 347–352]; an explanation as to why this is so is given. Moreover, we also give some questions to be discussed.
