An Entourage Approach to the Contraction Principle in Uniform Spaces Endowed with a Graph [PDF]
, 2013 In this paper, we study Banach contractions in uniform spaces endowed with a graph and give some sufficient conditions for a mapping to be a Picard operator. Our main results generalize some results of [J.

Duality for Evolutionary Equations With Applications to Null Controllability
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We study evolutionary equations in exponentially weighted L2$$ {\mathrm{L}}^2 $$‐spaces as introduced by Picard in 2009. First, for a given evolutionary equation, we explicitly describe the ν$$ \nu $$‐adjoint system, which turns out to describe a system backwards in time. We prove well‐posedness for the ν$$ \nu $$‐adjoint system. We then apply

The Theory of Reich's Fixed Point Theorem for Multivalued Operators
Fixed Point Theory and Applications, 2010 The purpose of this paper is to present a theory of Reich's fixed point theorem for multivalued operators in terms of fixed points, strict fixed points, multivalued weakly Picard operators, multivalued Picard operators, data dependence of the fixed ...

Picard-Jungck Operator for a Pair of Mappings and Simulation Type Functions
Mathematics, 2019 In this manuscript, we propose a new class of Picard-Jungck operators for a pair of mappings on complete metric spaces by taking into account of the C G -simulation function. Also, some new results for the existence of such operators for a pair of

A Functional Analytic Perspective to the div-curl Lemma [PDF]
, 2017 We present an abstract functional analytic formulation of the celebrated $\dive$-$\curl$ lemma found by F.~Murat and L.~Tartar. The viewpoint in this note relies on sequences for operators in Hilbert spaces.

Losing Control: The Erosion of Disciplinary and Pastoral Power in Accounting Firms
Contemporary Accounting Research, EarlyView.ABSTRACT Accounting firms have traditionally operated as both elite and reinventive institutions that offer a structured and prestigious career path and enforce a deeply transformative socialization process for auditors. However, recent labor market shifts and evolving work preferences are challenging this regime of power, with significant implications

When Knowledge Is Power: Leveraging Green Innovation Through Employee Training
International Journal of Training and Development, EarlyView.ABSTRACT This paper aims to examine the relationship between investments in employee training and green innovation outcomes in German firms. The study investigates how these training expenditures influence the development and implementation of innovations that lead to environmental benefits, such as reduced energy consumption or emissions.

Well-posedness via Monotonicity. An Overview
, 2014 The idea of monotonicity (or positive-definiteness in the linear case) is shown to be the central theme of the solution theories associated with problems of mathematical physics.

Unequal Solidarity: Club Rules and Crisis Support in the European Polity
JCMS: Journal of Common Market Studies, EarlyView.Abstract Is European solidarity during crises due to common or close identities? Or do Europeans punish rule‐breaking countries by showing them less solidarity? Research on the determinants of European solidarity increasingly focuses on ‘solidarity to’, how givers' attitudes are shaped by their perceptions of receiving member states.

On the convergence of Lupaş (p,q) $(p,q)$-Bernstein operators via contraction principle
Journal of Inequalities and Applications, 2019 The present paper deals with the limit behavior of iterates of Lupaş q- and (p,q) $(p,q)$-Bernstein operators. We obtain the convergence for Lupaş q- and (p,q) $(p,q)$-Bernstein operators by using the contraction principle.
