Generalized multivalued $F$-weak contractions on complete metric spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2015
In this paper,  we introduce the notion of  generalized multivalued  $F$- weak contraction and we prove some fixed point theorems related to introduced  contraction for multivalued mapping in complete metric spaces.

On the effect of alpha-admissibility and theta-contractivity to the existence of fixed points of multivalued mappings

open access: yesNonlinear Analysis, 2016
In this study, we give some fixed point results for multivalued mappings using α-admissibility and θ-contractivity of multivalued mappings on complete metric spaces.

Exploring New Chemical Paths in Quantum AI: Preliminary Accomplishments and Future Perspectives

open access: yesAdvanced Quantum Technologies, EarlyView.
Two new strategies derived from Chemical AI to promote the advancement of sustainable quantum technologies are presented and discussed. The first strategy relies on the chemical implementation of molecular fuzzy sets, which are quantum mixed states associated with chemical microheterogeneous systems. The second strategy relies on photochromic compounds

Common Fixed-Point Problem for a Family Multivalued Mapping in Banach Space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
It is our purpose in this paper to prove two convergents of viscosity approximation scheme to a common fixed point of a family of multivalued nonexpansive mappings in Banach spaces.

Entanglement Swapping for Partially Entangled Qudits and the Role of Quantum Complementarity

open access: yesAdvanced Quantum Technologies, EarlyView.
The entanglement swapping protocol is extended to partially entangled qudit states and analyzed through complete complementarity relations. Analytical bounds on the average distributed entanglement are established, showing how the initial local predictability and entanglement constrain the operational distribution.

Fixed-Point Theorem for Multivalued Quasi-Contraction Maps in a V-Fuzzy Metric Space

open access: yesAbstract and Applied Analysis, 2020
In this paper, we introduce the concept of a set-valued or multivalued quasi-contraction mapping in V-fuzzy metric spaces. Using this new concept, a fixed-point theorem is established. We also provide an example verifying and illustrating the fixed-point

Algorithmic Aspect and Convergence Analysis for System of Generalized Multivalued Variational-like Inequalities

open access: yesMathematics, 2022
The main aim of this paper is twofold. Our first objective is to study a new system of generalized multivalued variational-like inequalities in Banach spaces and to establish its equivalence with a system of fixed point problems utilizing the concept of ...

Adoption of Minimum Tillage and Mid‐Season Drainage in Rice Production and Their Impacts on Farm and Economic Performance

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the effects of two greenhouse gas (GHG) mitigation practices—minimum tillage and mid‐season drainage—on rice farmers' farm performance (e.g., crop yield and risk) and economic outcomes (e.g., income and vulnerability).

Densely Defined Selections of Multivalued Mappings [PDF]

open access: yesTransactions of the American Mathematical Society, 1994
Summary: Rather general sufficient conditions are found for a given multivalued mapping \(F : X \to Y\) to possess an upper semicontinuous and compact-valued selection \(G\) which is defined on a dense \(G_\delta\)-subset of the domain of \(F\). The case when the selection \(G\) is single-valued (and continuous) is also investigated.

Cryptocurrency Bubbles and Costly Mining

open access: yesInternational Economic Review, EarlyView.
ABSTRACT This paper develops a model of a cryptocurrency by incorporating mining into the otherwise standard search‐theoretic monetary framework. As usual, multiple equilibria exist. To obtain a sharp prediction on whether a cryptocurrency' s value will last in the future, I propose a notion of equilibrium refinement based on the feature that mining ...
