Periodica Mathematica Hungarica Aims and scope Submit manuscript

Abstract

Two theorems concerning common fixed points of set-valued mappings and singlevalued mappings are established using the concept of weak commutativity indebted to the second author. The first theorem generalizes a recent result of the first author and suitable examples are also given.
