Coincidences and Fixed Points of Nonself Hybrid Contractions

open access: yesJournal of Mathematical Analysis and Applications, 2001
Let \((X, d)\) be a complete metrically convex metric space, \(K\) a non-empty closed subset of \(X\), \(F, G: K \to CL(X), S, T\) selfmaps of \(K\). The hybrid contractions in this paper satisfy the inequality \(H(Fx, Gy) \leq \alpha d(Tx, Sy) + \beta[d(Tx, Fx) + d(Sy, Gy)] + \gamma[d(Tx, Gy) + d(Sy, Fx)]\) for each \(x,y \in X\), where \(\alpha ...

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Multivalued generalizations of fixed point results in fuzzy metric spaces

open access: yesNonlinear Analysis, 2016
This paper attempts to prove fixed and coincidence point results in fuzzy metric space using multivalued mappings. Altering distance function and multivalued strong {bn}-fuzzy contraction are used in order to do that.

Existence of coupled coincidence best proximity point [PDF]

open access: yesSurveys in Mathematics and its Applications
This work of optimality is engaged with couple coincidence best proximity point. We have developed some optimal results where control functions and non-linear weak inequalities are evident. Further using our results, we establish some fixed point results.

C*-Algebra Valued Fuzzy Soft Metric Spaces and Results for Hybrid Pair of Mappings

open access: yesAxioms, 2019
In this paper, we establish some results on coincidence point and common fixed point theorems for a hybrid pair of single valued and multivalued mappings in complete C * -algebra valued fuzzy soft metric spaces.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Coupled Coincidence Point and Coupled Fixed Point Theorems via Generalized Meir-Keeler Type Contractions

open access: yesAbstract and Applied Analysis, 2012
We prove coupled coincidence point and coupled fixed point results of 𝐹∶𝑋×𝑋→𝑋 and 𝑔∶𝑋→𝑋 involving Meir-Keeler type contractions on the class of partially ordered metric spaces. Our results generalize some recent results in the literature.

Generalized (ψ,α,β)—Weak Contractions for Initial Value Problems

open access: yesMathematics, 2019
A class of generalized ( ψ , α , β ) —weak contraction is introduced and some fixed-point theorems in a framework of partially ordered metric spaces are proved.
