Remark on the system of nonlinear variational inclusions

open access: yesArab Journal of Mathematical Sciences, 2014
We prove the existence of a solution to the system of nonlinear variational inclusions problem. We provide examples of applications related to a coupled best approximations theorem for multivalued mappings and a multivalued coupled coincidence point.

Common fixed, coupled coincidence and common coupled fixed point results in hyperbolic valued metric spaces

open access: yesBoletim da Sociedade Paranaense de Matemática, 2022
In this paper, we obtain existence of unique common fixed point for a contraction mapping on hyperbolic valued metric spaces, and also develop some coupled coincidence point and common coupled fixed point results for two mappings satisfying various ...

A thermodynamically consistent derivation of a frictional-damage cohesive-zone model with different mode i and mode II fracture energies [PDF]

open access: yes, 2015
The present paper deals with the derivation of an interface model characterized by macroscopic fracture energies which are different in modes I and II, the macroscopic fracture energy being the total energy dissipated per unit of fracture area.

Coincidence point theorems for $\varphi$-$\psi$-contraction mappings in metric spaces involving a graph

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2016
Some new coupled coincidence and coupled common fixed point theorems for $\varphi$-$\psi$-contraction mappings are established. We have also an application to some integral system to support the results.

Asymptotically Coupled Coincidence Points and Asymptotically Coupled Fixed Points in Fuzzy Semi-Metric Spaces

open access: yesAxioms, 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. In this case, the desired results are separately investigated based on four different types of triangle inequalities. The uniqueness

Three Point Functions of Chiral Primary Operators in d=3, N= 8 and d=6, N=(2,0) SCFT at Large N [PDF]

open access: yes, 1999
We use the AdS/CFT correspondence to calculate three point functions of chiral primary operators at large N in d=3, N=8 and d=6, N=(2,0) superconformal field theories.

Coincidence of Fixed Points with Mixed Monotone Property

open access: yesمجلة بغداد للعلوم, 2023
The purpose of this paper is to introduce and prove some coupled coincidence fixed point theorems for self mappings satisfying -contractive condition with rational expressions on complete partially ordered metric spaces involving altering distance ...

Proof of concept of an imaging system demonstrator for PET applications with SiPM [PDF]

open access: yes, 2013
A PET imaging system demonstrator based on LYSO crystal arrays coupled to SiPM matrices is under construction at the University and INFN of Pisa. Two SiPM matrices, composed of 8×8 SiPM pixels, and 1,5 mm pitch, have been coupled one to one to a LYSO ...

Coupled coincidence point theorems for compatible mappings in ordered uniform space [PDF]

open access: yesMiskolc Mathematical Notes, 2015
In this paper, we use the order relation on uniform spaces defined by [5] to introduce the notion of compatibility of mappings in an ordered uniform space and use this notion to establish coupled coincidence point theorems to ordered uniform space. An example is also given.
