Coincidence and fixed points for hybrid strict contractions

[摘要] We define the property (E. A) for single-valued and multivalued mappings and introduce the notion of T-weak commutativity for a hybrid pair (f, T) of single-valued and multivalued maps. We obtain some coincidence and fixed point theorems for this class of maps and derive, as application, an approximation theorem. (C) 2004 Elsevier Inc. All rights reserved.
