In this paper, we define different ansatz equations to study two classes of high‐order nonlinear Schrödinger equations. The concrete forms of soliton solutions of these two classes of equations are obtained by using this equation. This paper briefly summarizes and explains the method used and applies it to two classes of specific equations. Finally, the concrete form of solutions and the necessary conditions for the existence of solutions are obtained, and pictures are added to assist understanding.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
