NOTE ON JENSEN AND PEXIDER FUNCTIONAL EQUATIONS
Demonstratio Mathematica, 1999 The Jensen functional equation \[ 2f\left({x+y \over 2}\right) =f(x)+f(y) \tag{1} \] is solved in the case where \(f:M\to S\), \(M\) is an Abelian semigroup with the division by \(2,S\) is an abstract convex cone satisfying the cancellation law. The result when applied to a set-valued version of (1) (where \(f\) takes values from the set \(ccl(X)\) of ...

Asymptotic behavior of alternative Jensen and Jensen type functional equations
Bulletin des Sciences Mathématiques, 2005 Let \(X\) be a real normed space and \(Y\) be a real Banach space. A mapping \(A : X \to Y\) is called (i) alternative additive of the first form if \(A(x + y) + A(x - y) = -2A(-x)\); (ii) alternative additive of the second form if \(A(x + y) - A(x - y) = -2A(-y)\); (iii) alternative Jensen if \(A( - \frac{x + y}{2}) = - \frac{1}{2}(A(x) + A(y))\); (iv)

The Anatomical Record, EarlyView.Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines the determinants of firms' propensity to adopt green buildings in the Euro Stoxx 300 and the S&P 500 indices, during 2012–2023. Using random forest binary classifiers, we assess the relative importance of financial, sectoral, geographic, and climate governance predictors and uncover nonlinear relationships often overlooked ...

On a Local Stability of the Jensen Functional Equation
Demonstratio Mathematica, 1989 The problem of stability of Cauohy's functional equation on a restriot domain D in R has a positive answer [5]. In this paper we shall show that Cauchy's functional equation and Jensen's functional equation on a restriot domain D being some subset of R are stable.

Complex Firms, Controversial Outcomes: Global Evidence on ESG Failures and Remedies
Business Strategy and the Environment, EarlyView.ABSTRACT We examine whether business complexity increases firms' exposure to negative environmental, social, and governance (ESG) outcomes, specifically ESG controversies, using a global panel of firms from 37 countries over the period 2002–2021.

Business Strategy and the Environment, EarlyView.ABSTRACT The agri‐food sector is vital to economic development, but it exerts significant environmental and social pressures. This study draws on the natural resource‐based view. It investigates the strategic sustainability‐performance nexus in the global food and beverage industry using a longitudinal dataset (2013–2023) of 633 firms across the EU ...

On a local form of Jensen's functional equation
Aequationes Mathematicae, 1985 A function f:(a,b)\(\rightharpoonup R\) is said to be locally Jensen at \(x\in (a,b)\) if there exists \(\delta >0\) such that (1) \(1/2(f(x+h)+f(x- h))=f(x)\) holds for ...
