Abstract: We investigate attractors for compact sets by considering a certain quotient space. The following theorem is included. Let $ f:G \to G$, G a closed convex subset of a Banach space, f a mapping satisfying (i) there exists $ M \subset G$ which is an attractor for compact sets under f; (ii) the family $ \{ {f^n}\} _{n = 1}^\infty $ is equicontinuous. Then f has a fixed point.
