Optimal Approximate Solution of Coincidence Point Equations in Fuzzy Metric Spaces
Mathematics, 2019 The purpose of this paper is to introduce α f -proximal H -contraction of the first and second kind in the setup of complete fuzzy metric space and to obtain optimal coincidence point results.

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

On common fixed point of generalized contractive mappings in metric spaces [PDF]
Surveys in Mathematics and its Applications, 2012 Existence of common fixed points is established for two self-mappings satisfying a generalized contractive condition. The presented results generalize several well known comparable results in the literature. We also study well-posedness of a common fixed

Carpathian Journal of Mathematics, 2019 We introduce the class of KC-contraction mappings and prove some coincidence point theorems for these contractions in JS-metric spaces endowed with a directed graph.

On Changing Fixed Points and Coincidences to Roots [PDF]
Proceedings of the American Mathematical Society, 1992 The coincidence problem, finding solutions to f ( x ) = g ( x ) f(x) = g(x) , can sometimes be converted to a root problem, finding solutions to σ ( x ) = a \sigma (x) = a .

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

FIXED POINTS AND COINCIDENCES IN TORUS BUNDLES [PDF]
Journal of Topology and Analysis, 2011 Minimum numbers of fixed points or of coincidence components (realized by maps in given homotopy classes) are the principal objects of study in topological fixed point and coincidence theory. In this paper, we investigate fiberwise analoga and present a general approach e.g. to the question when two maps can be deformed until they are coincidence free.

Relational Meir-Keeler Contractions and Common Fixed Point Theorems
Journal of Function Spaces, 2022 In this article, we prove some coincidence and common fixed point theorems under the relation-theoretic Meir-Keeler contractions in a metric space endowed with a locally finitely T-transitive binary relation.

Coincidence Points in Generalized Metric Spaces [PDF]
Set-Valued and Variational Analysis, 2014 Covering mappings in generalized metric spaces are considered. The coincidence points theorems for single-valued and set-valued mappings are proved. The results obtained are applied to the problem of solvability of equations in the space of continuous functions. © 2014, Springer Science+Business Media Dordrecht.
