Abstract

In this paper, we establish the existence of global smooth solutions for the Landau–Lifshitz type system on a finite interval $[0,L]$. The proof is based on the technique of finite difference-differential and a priori estimates. Our result matches the known result on periodic boundary condition in $[\href{https://doi.org/10.3934/dcds.1999.5.729}{7}]$.
