In this paper, we consider the nonlocal non‐autonomous evolution problems where Ω is a bounded smooth domain inR N , N ≥1, β is a positive constant, the coefficient a is a continuous bounded function on R , and K is an integral operator with symmetric kernel ( Ku ) ( x ) : = ∫R NJ ( x , y ) u ( y ) dy , being J a non‐negative function continuously differentiable onR N × R Nand∫R NJ ( · , y ) dy = 1 . We prove the existence of global pullback attractor, and we exhibit a functional to evolution process generated by this problem that decreases along of solutions. Assuming the parameter β is small enough, we show that the origin is locally pullback asymptotically stable. Copyright © 2014 John Wiley & Sons, Ltd.
