The variants of auxiliary equation method, which are based on Mathieu, Bernoulli and classical Riccati equations, are used for these equations. Obtained solutions are discussed and illustrated in details. Although studies on the third-order equations have been intriguing for many years, the proposed equations were not studied in the literature. We believe that the proposed results will be key part of further analytical and numerical studies for waves in the dispersive medium with reaction.en10.1007/s11071-017-3878-2info:eu-repo/semantics/closedAccessAuxiliary equation methodBernoulli equationMathieu equationTanh-methodThird-order equationTravelling wave solutionsTraveling-Wave SolutionsAuxiliary EquationRational SolutionsSoliton-SolutionsArticle911421426Q1WOS:0004188389000272-s2.0-85032384681Q1
