    EXISTENCE OF FIXED POINTS FOR NEW PRESIC TYPE MULTIVALUED OPERATORS
    (Yokohama Publ, 2017) Ali, Muhammad Usman; Kamran, Tayyab; Karapinar, Erdal
    In this paper, we shall generalize the convergence theorem introduced by Presic in 1965, by introducing the notions of alpha-Presic type contractive multivalued operators. We shall also construct some examples to prove the generality of our results.

    An Approach To Existence of Fixed Points of Generalized Contractive Multivalued Mappings of Integral Type Via Admissible Mapping
    (Hindawi Ltd, 2014) Ali, Muhammad Usman; Kamran, Tayyab; Karapinar, Erdal
    We investigate the existence of a fixed point of certain contractive multivalued mappings of integral type by using the admissible mapping. Our results generalize the several results on the topic in the literature involving Branciari, and Feng and Liu. We also construct some examples to illustrate our results.

    Fixed Point Theorems in Uniform Space Endowed With Graph
    (Univ Miskolc inst Math, 2017) Ali, Muhammad Usman; Fahimuddin; Kamran, Tayyab; Karapinar, Erdal
    In this paper, we shall introduce the concepts of F-G-contraction and psi(G)-contraction in uniform space endowed with graph to investigate the existence of a fixed point of mappings satisfying these notions. We shall also introduce a common fixed point theorem for pair of mappings satisfying the notion of psi(G)-contraction in uniform space endowed with graph.
