    On Fixed Point Theorems For Multivalued Mappings Of Feng-Liu Type
    (Korean Mathematical Soc, 2015) Altun, Ishak; Minak, Guelhan
    In the present paper, considering the Jleli and Samet's technique we give many fixed point results for multivalued mappings on complete metric spaces without using the Pompeiu-Hausdorff metric. Our results are real generalization of some related fixed point theorems including the famous Feng and Liu's result in the literature. We also give some examples to both illustrate and show that our results are proper generalizations of the mentioned theorems.

    Recent developments about multivalued weakly Picard operators
    (Belgian Mathematical Soc Triomphe, 2015) Minak, Guelhan; Altun, Ishak; Romaguera, Salvador
    In the present paper, considering a recent technique, which is used by Wardowski [24] for fixed points of single-valued mappings, we give a new and general class of multivalued weakly Picard operators on complete metric spaces and show that the class of multivalued almost contractions (both linear and nonlinear cases in the sense of Berinde and Berinde [9]) is a proper subset of this new class. We also give a nontrivial example showing this fact.
