Mathematics, 2022 In this study, we obtain certain coupled fixed-point results for generalized contractions involving two control functions in a controlled metric space. Additionally, we establish some coupled fixed-point results in graph-enabled controlled metric spaces.

The contraction mapping principle [PDF]
, 1986 In the world of mathematics, it is often necessary to approximate the solution to a problem by using an iterative method. One such method, not totally dependent on the initial guess, is the contraction mapping method.

Proceedings of the American Mathematical Society, 1973 The Cauchy condition for convergence of a contractive iteration in a complete metric space is replaced by an equivalent functional condition. Many generalizations of the Banach-Neumann contractive mapping principle follow.

Some Fixed-Point Results for a -Weak Contraction in -Metric Spaces
Abstract and Applied Analysis, 2012 We introduce the concepts of a -weak contraction mapping of types and and we establish some fixed point theorems for a -weak contraction mapping of types and in complete -metric spaces. Our results generalize several well-known comparable results in

Journal of Function Spaces, 2022 This paper establishes the reality of a fixed point of Kannan’s prequasinorm contraction mapping on the variable exponent function space of complex variables, demonstrating that it satisfies the property (R) and possesses a prequasinormal structure.

Contractibility of a persistence map preimage [PDF]
Journal of Applied and Computational Topology, 2020 AbstractThis work is motivated by the following question in data-driven study of dynamical systems: given a dynamical system that is observed via time series of persistence diagrams that encode topological features of snapshots of solutions, what conclusions can be drawn about solutions of the original dynamical system? We address this challenge in the

Determining fuzzy distance through non-self fuzzy contractions [PDF]
Yugoslav Journal of Operations Research, 2019 In the present work we solve the problem of finding the fuzzy distance between two subsets of a fuzzy metric space for which we use a non-self fuzzy contraction mapping from one set to the other.
