e-Distance in Menger PGM Spaces with an Application
(MDPI, 2020-12-30)
The main purpose of the present paper is to define the concept of an e-distance (as a generalization of r-distance) on a Menger PGM space and to introduce some of its properties. Moreover, some coupled fixed point results, ...
Subsurface chemical nanoidentification by nano-FTIR spectroscopy
(Nature, 2020-07-03)
Nano-FTIR spectroscopy based on Fourier transform infrared near-field spectroscopy allows for label-free chemical nanocharacterization of organic and inorganic composite surfaces. The potential capability for subsurface ...
Optimal Perturbation Iteration Method for Solving Fractional Model of Damped Burgers’ Equation
(MDPI, 2020-06-04)
The newly constructed optimal perturbation iteration procedure with Laplace transform is applied to obtain the new approximate semi-analytical solutions of the fractional type of damped Burgers’ equation. The classical ...
Some New Fuzzy Fixed Point Results with Applications
(MDPI, 2020-06-17)
The aim of this article is to establish some fixed point results for fuzzy mappings and derive some corresponding multivalued mappings results of literature. For this purpose, we define some new and generalized contractions ...
On the Topology Induced by C*-Algebra-Valued Fuzzy Metric Spaces
(MDPI, 2020-06-03)
We define the notion of <inline-formula> <math display="inline"> <semantics> <msup> <mi>C</mi> <mo>*</mo> </msup> </semantics> </math> </inline-formula>-algebra-valued fuzzy metric spaces and we study the topology induced ...
Magnetoimpedance and Stress-Impedance Effects in Amorphous CoFeSiB Ribbons at Elevated Temperatures
(MDPI, 2020-07-19)
The temperature dependencies of magnetoimpedance (MI) and stress impedance (SI) were analyzed both in the as-quenched soft magnetic Co68.5Fe4Si15B12.5 ribbons and after their heat treatment at 425 K for 8 h. It was found ...
Applying Fixed Point Techniques to Stability Problems in Intuitionistic Fuzzy Banach Spaces
(MDPI, 2020-06-15)
In this paper we investigate Hyers-Ulam-Rassias stability of certain nonlinear functional equations. Considerations of such stabilities in different branches of mathematics have been very extensive. Again the fuzzy concepts ...
Collective near-field coupling and nonlocal phenomena in infrared-phononic metasurfaces for nano-light canalization
(Nature, 2020-07-21)
Polaritons - coupled excitations of photons and dipolar matter excitations - can propagate along anisotropic metasurfaces with either hyperbolic or elliptical dispersion. At the transition from hyperbolic to elliptical ...
Some New Results on Coincidence Points for Multivalued Suzuki-Type Mappings in Fairly Complete Spaces
(MDPI, 2020-03-17)
In this paper, we introduce Suzuki-type generalized and modified proximal contractive mappings. We establish some coincidence and best proximity point results in fairly complete spaces. Also, we provide coincidence and ...
New Fixed Point Theorems in Orthogonal F -Metric Spaces with Application to Fractional Differential Equation
(MDPI, 2020-05-19)
We present the notion of orthogonal F
-metric spaces and prove some fixed and periodic point theorems for orthogonal ⊥Ω
-contraction. We give a nontrivial example to prove the validity of our result. Finally, as ...
