Abstract:We study the long time behavior of the following non-autonomous reaction-diffusion equation defined on the unbounded domain Rn with a linear memory term and external terms which are unbounded in a phase space u/t-Δu+λu-∫∞0k(s)Δu(t-s)ds=f(x,u)+g(x,t). We use the uniform estimates method to prove the existence of the pullback attractor for the above equation in phase space X0=L2(Rn)×M0 and X1=H1(Rn)×M1,respectively.
Keywords:pullback attractor  memory term  asymptotic compactness  non-autonomous equation
