Fixed point results for multivalued mappings of Ciric type via F-contractions on quasi metric spaces
Shatanawi, Wasfi; Altun, Ishak; Dag, Hacer (DE GRUYTER POLAND SP Z O O, 2020)In this paper, we present some fixed point results for multivalued mappings with both closed values and proximinal values on left K-complete quasi metric spaces. We also provide a nontrivial example to illustrate our results. -
Multivalued F-Contractions On Complete Metric Spaces
Altun, Ishak; Minak, Gulhan; Dag, Hacer (Yokohama Publ, 2015)In the present paper, we introduce the concept of multivalued F-contraction mappings and give some fixed point results, which generalize some multivalued fixed point theorems including Nadler's. Also, we give an illustrating ... -
Nonlinear proximinal multivalued contractions on quasi-metric spaces
Altun, Ishak; Dag, Hacer (Springer Basel Ag, 2017)In this paper, taking into account the concept of proximinal set, we obtain some new fixed point results for nonlinear proximinal multivalued contractions on some kind of complete quasi-metric spaces. Also, we present some ...
