Abstract

This paper mainly discusses the existence and uniqueness of solutions for the high-order Landau-Lifshitz type systems. Firstly, we consider the periodic initial value problem for the fourth-order Landau-Lifshitz type equation. Then we explore the existence and uniqueness of a global smooth solution for the high-order Landau-Lifshitz type equation. The proof is based on the technique of finite difference-differential methods and the \textit{a priori} estimates.

Keywords
