Bifurcation of new optical solitary wave solutions for the nonlinear long-short wave interaction system via two improved models of (G′G) expansion method

Abstract

This study performs two recent methods on the nonlinear long-short wave interaction system (NLSWIS) to obtain novel formulas of solitary solutions representing an optical feld that does not alter by multiplication a sensitive balance between the diferent terms impacts in the medium. Elastic medium is defned as the medium that can adjust in the fgure due to a deforming strength and come back shape to its original form when the force eliminates. The wave is produced by vibrations that are a consequence of acoustic power. Also known as the sound wave, or acoustic wave. For examples of elastic mediums are air, water and so on. The improved ( G′ G ) expansion method and novel ( G′ G ) expansion method are implemented, which are considered as two general methods in this feld. Applying these methods to many nonlinear partial diferential equations gives diverse and diferent forms and confguration solutions that allow users of those two methods a large number of solutions that provide broader scope to use.
