  • Frum-ketkov type multivalued operators 
    Karapınar, Erdal; Petruşel, Adrian; Petruşel, Gabriela (2021)
    Let (M, d) be a metric space, X ⊂ M be a nonempty closed subset and K ⊂ M be a nonempty compact subset. By definition, an upper semi-continuous multivalued operator F: X → P (X) is said to be a strong Frum-Ketkov type ...
  • On admissible hybrid geraghty contractions 
    Karapınar, Erdal; Petruşel, Adrian; Petruşel, Gabriela (2020)
    In this manuscript, we introduce the notion of admissible hybrid Geraghty contraction and we investigate the existence of fixed points of such mappings in the setting of complete metric spaces. Our results not only extend ...
  • On hybrid contractions in the context of quasi-metric spaces 
    Fulga, Andreea; Karapınar, Erdal; Petruşel, Gabriela (2020-05-01)
    In this manuscript, we will investigate the existence of fixed points for mappings that satisfy some hybrid type contraction conditions in the setting of quasi-metric spaces. We provide examples to assure the validity of ...
