Fixed Point Theorems on Almost (<i>φ</i>,<i>θ</i>)-Contractions in Jleli-Samet Generalized Metric Spaces

Abstract

In this paper, we present extensions of some classic results regarding the existence and uniqueness of fixed points of operators fulfilling generalized contractive conditions defined by sums involving some functions with suitable properties in the setting of Jleli–Samet generalized metric spaces. As a consequence, some known results in the literature are obtained. Examples are provided to prove the usability of our developments.
