Let be a convex, weakly compact subset of a locally convex Hausdorff space and be a continuous multifunction from its weak topology to . let be a continuous seminorm on and for subsets , of let . In this paper, sufficient conditions are developed for the existence of an satisfying . The result is then used to prove several fixed point theorems.
