Abstract. In this paper we study autonomous evolution inclusions in an evolution triple, and satisfying one sided Lipschitzian condition with some negative constant. It is known that the solution set is compact on every bounded interval. Using this fact we prove the existence of a unique strong forward attractor and a unique strong backward attractor when the one sided Lipschitz constant is positive. As a corollary some surjectivity and fixed point results are proved. An example of a parabolic system, satisfying our assumptions is discussed.
