 note = {We give an example which says that Mizoguchi-Takahashi’s fixed pointtheorem for set-valued mappings is a real generalization of Nadler’s. The example isa counterexample to a recent result in Eldred, Anuradha and Veeramani [J. Math.Anal. Appl. (2007), doi:10.1016/j.jmaa.2007.01.087]. We also give a very simple proofof Mizoguchi-Takahashi’s theorem.},
