Generalized cyclic contractions and coincidence points involving a control function on partial metric spaces [PDF]
Arab Journal of Mathematical Sciences, 2021 Purpose – In this paper, we use the notion of cyclic representation of a nonempty set with respect to a pair of mappings to obtain coincidence points and common fixed points for a pair of self-mappings satisfying some generalized contraction- type ...

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 ...

Axioms, 2022 Asymptotically coupled coincidence points and asymptotically coupled fixed points in fuzzy semi-metric spaces are studied in this paper. The fuzzy semi-metric space is taken into account, which lacks symmetric conditions.

Exploring the cosmological dark matter coincidence using infrared fixed points [PDF]
Physical Review D, 2022 The asymmetric dark matter (ADM) paradigm is motivated by the apparent coincidence between the cosmological mass densities of visible and dark matter, $\Omega_\mathrm{DM} \simeq 5\Omega_\mathrm{VM}$.

A Random Coincidence Point Theorem
Journal of Mathematical Analysis and Applications, 2000 Let \((\Omega ,\Sigma)\) be a measurable space, \(M\) a weakly compact subset of a Banach space \(X\), \(f:\Omega\times M\to M\) and \(T:\Omega\times M\to 2^{M}\) random operators. The main result of this note gives sufficient conditions for the existence of a random coincidence point of \(T\) and \(f\), i.e., a measurable mapping \(\xi:\Omega\to M ...

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 .

On random coincidence point theorems [PDF]
Topological Methods in Nonlinear Analysis, 2005 The author obtains a few coincidence point theorems for a pair of single-valued and multivalued non-commuting random operators. The main result is a mild extension of the work of the author and \textit{A. Latif} [J. Math. Anal. Appl. 245, No.~2, 633--638 (2000; Zbl 0970.60074)]. Some special cases of the work of other authors are also discussed.
