Summary:We study the long-time behavior of solution for the m -Laplacian equation ut -div(|∇u|m-2 ∇u)+λ|u|m-2 u+f(x,u)=g(x) in RN ×R+ , in which the nonlinear term f(x,u) is a function like f(x,u)=-h(x)|u|q-2 u with h(x)≥0 , 2≤q<m , or f(x,u)=a(x)|u|α-2 u-h(x)|u|β-2 u with a(x)≥h(x)≥0 and α>β≥m . We prove the existence of a global (L2 (RN ),Lp (RN )) -attractor for any p>m .
