      Vujaković, Jelena; Mitrović, Slobodanka; Mitrović, Zoran; Radenović, Stojan (MDPI (Basel, Switzerland), 2020-09-21)
      In the paper, we consider some fixed point results of F-contractions for triangular α-admissible and triangular weak α-admissible mappings in metric-like spaces. The results on F-contraction type mappings in the context ...
    • On some F−contraction of Piri-Kumam-Dung type mappings in metric spaces 

      Vujaković, Jelena; Radenović, Stojan (2020-07-15)
      This paper establishes some new results of Piri–Kumam–Dung-type mappings in a complete metric space.Тhe goal was to improve the already published results. Methods: Using the property of a strictly increasing function as ...
    • Some New Results for Jaggi-W-Contraction-Type Mappings on b-Metric-like Spaces 

      Mitrović, Slobodanka; Parvaneh, Vahid; De la Sen, Manuel; Vujaković, Jelena; Radenović, Stojan (MDPI (Basel, Switzerland), 2021-08-12)
      In this article, we generalize, improve, unify and enrich some results for Jaggi-W-contraction-type mappings in the framework of b-metric-like spaces. Our results supplement numerous methods in the existing literature, and ...
