摘　　要：In this paper, we show the existence of weak solutions for a higher order nonlinear elliptic equation. Our main method is to show that the evolution operator satisfies the fixed point theorem for Banach semilattice.In this paper, we show the existence of weak solutions for a higher order nonlinear elliptic equation.
