A general unique common fixed point theorem for hybrid pairs of mappings in metric spaces [PDF]

open access: yesSurveys in Mathematics and its Applications, 2016
The purpose of this paper is to prove a general unique common fixed point theorem for two pairs of mappings using Hausdorff - Pompeiu metric, which generalizes, in a correct form, the results from [H. Bouhadjera, A. Djoudi and B.

Does Accounting Scope 3 Emissions Improve Sustainable Business Outcomes? Evidence From the S&P 500 Technology Companies

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Corporate sustainability efforts increasingly emphasize Scope 3 emissions due to their substantial share of total corporate carbon footprints. However, reporting these emissions remains inconsistent, limiting transparency and comparability across firms.

From Two‐Electron to Four‐Electron System: Electrolyte Regulation for Advanced Aqueous Zn–I2 Batteries

open access: yesCarbon Energy, EarlyView.
This review systematically summarizes recent progress in electrolyte‐regulated aqueous Zn–I2 batteries (AZIBs). It outlines the fundamentals of AZIBs along with their main challenges, and then analyzes electrolyte‐engineering strategies that improve both two‐ and four‐electron reactions.

Common Fixed Point Theorems on Weakly Contractive and Nonexpansive Mappings

open access: yesFixed Point Theory and Applications, 2008
A family of commuting nonexpansive self-mappings, one of which is weakly contractive, are studied. Some convergence theorems are established for the iterations of types Krasnoselski-Mann, Kirk, and Ishikawa to approximate a common fixed point. The error

Commutator maps, measure preservation, and 𝑇-systems [PDF]

open access: yesTransactions of the American Mathematical Society, 2009
Let G G be a finite simple group. We show that the commutator map α : G × G → G \alpha :G \times G \rightarrow G is almost equidistributed as | G | → ∞ |G| \rightarrow \infty .

A priori bounds for the generalised parabolic Anderson model

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We show a priori bounds for solutions to (∂t−Δ)u=σ(u)ξ$(\partial _t - \Delta) u = \sigma (u) \xi$ in finite volume in the framework of Hairer's Regularity Structures [Invent Math 198:269–504, 2014]. We assume σ∈Cb2(R)$\sigma \in C_b^2 (\mathbb {R})$ and that ξ$\xi$ is of negative Hölder regularity of order −1−κ$- 1 - \kappa$ where κ<κ¯$\kappa <

Compatible mappings and common fixed points (2)

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
A common fixed point theorem of S.L. and S.P. Singh is generalized by weakening commutativity hypotheses and by increasing the number of functions involved.

Ngos' Contributions to Innovation: Innovation Enablers or Lead Innovators?

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores how non‐governmental organisations (NGOs) engage with innovation processes. Drawing on a comparative case study of two NGOs working in water sustainability, the paper analyses NGO involvement across seven stages of the innovation process.

A Note on Common Fixed Point Results in Uniformly Convex Hyperbolic Spaces

open access: yesJournal of Mathematics, 2013
It is shown that the notion of mappings satisfying condition (K) introduced by Akkasriworn et al. (2012) is weaker than the notion of asymptotically quasi-nonexpansive mappings in the sense of Qihou (2001) and is weaker than the notion of pointwise ...
