摘要


Let X be a complete, metrically convex metric space, K a closed convex subset of X, CB(X) the set of closed and bounded subsets of X. Let F: K→CB(X) satisfying definition (1) below, with the added condition that Fx ⊆ K for each x ∈ ∂K. Then F has a fixed point in K. This result is an extension to multivalued mappings of a result of Ćirić [1].
