      Vujaković, Jelena; Mitrović, Slobodanka; Pavlović, Mirjana; Radenović, Stojan (MDPI (Basel, Switzerland), 2020-05-11)
      In this manuscript we discuss, consider, generalize, improve and unify several recent results for so-called F-contraction-type mappings in the framework of complete metric spaces. We also introduce (φ,F) -weak contraction ...
    • On Some New Contractive Conditions in Complete Metric Spaces 

      Vujaković, Jelena; Ljajko, Eugen; Pavlović, Mirjana; Radenović, Stojan (MDPI (Basel, Switzerland), 2021-01-07)
      One of the main goals of this paper is to obtain new contractive conditions using the method of a strictly increasing mapping F:(0,+∞)→(−∞,+∞). According to the recently obtained results, this was possible (Wardowski’s ...
