Nonclassical symmetries and analytic solutions to Kawahara equation

Abstract

<jats:p> The focus of this paper is on Kawahara equation(KE) which models diverse variety of waves enforced in many branches of applied sciences. Symmetries to the considered equation are successfully obtained by practicing nonclassical method. According to nonclassical symmetries, KE has been reduced to numerous ODEs. Further, these ODEs are treated such that new analytic solutions are determined by applying power series, ansätz and [Formula: see text]-expansion method. </jats:p>
