KKM mappings in metric type spaces. (English) Zbl 1321.54085
Summary: We discuss some recent results about KKM mappings in cone metric spaces. We also discuss the fixed point existence results of multivalued mappings defined on such metric spaces. In particular, we show that most of the new results are merely copies of the classical ones and do neither necessitate the underlying Banach space nor the associated cone.
