Abstract:
In this paper, we study the question of conditions for the existence and uniqueness of a fixed point of a mapping over a complete metric space. We first discuss the concepts of F-contraction and F∗-contraction in fixed point theory. These concepts, developed respectively by Wardowski and Piri with Kumam, have catalyzed significant research in various metric spaces. We then propose a generalization of these concepts, ρ−F-contraction and ρ−F∗-contraction, and demonstrate its effectiveness in ensuring the existence and uniqueness of fixed points. This new approach provides greater flexibility by including a function ρ that modulates the contraction, extending the applicability of F- and F∗-contractions. We conclude the paper with an example of a mapping that is a ρ−F-contraction and a ρ−F∗-contraction, respectively, and has a unique fixed point. However, this mapping does not satisfy the conditions of Wardowski and the conditions of Piri and Kumam.
