KKM property and fixed point theorems in metric spaces

[摘要] In this paper, first part, we establish some fixed point theorems for a k-set contraction map on the nearly-subadmissible subsets of a complete metric space. The second part, we deduce a generalization of the approximate fixed point theorem for the lower semicontinuous mappings on a metric space. (c) 2005 Elsevier Inc. All rights reserved.
