Efficiency in Pure‐Exchange Economies With Risk‐Averse Monetary Utilities

Mathematical Finance, Volume 36, Issue 1, Page 99-117, January 2026.
ABSTRACT We study Pareto efficiency in a pure‐exchange economy where agents' preferences are represented by risk‐averse monetary utilities. These coincide with law‐invariant monetary utilities, and they can be shown to correspond to the class of monotone, (quasi‐)concave, Schur concave, and translation‐invariant utility functionals. This covers a large

Continuous Selections For Almost Lower Semicontinuous Multifunctions [PDF]

, 2011
[[abstract]]In this paper, we obtain several new continuous selection theorems for almost lower semicontinuous multifunctions T on a paracompact topological space X, in the general noncompact and/or nonconvex settings.

Quantitative Nonlocal‐to‐Local Limits in Multispecies Interaction Systems via Relative Entropy and Modulated Energy

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
We derive quantitative convergence rates for nonlocal‐to‐local limits in a class of multispecies interaction systems with finite‐range kernels. The nonlocal model consists of coupled aggregation–diffusion equations in which intra‐ and interspecies interactions are mediated by short‐range convolution operators.

Nonautonomous attractors of skew-product flows with digitized driving systems

Electronic Journal of Differential Equations, 2001
The upper semicontinuity and continuity properties of pullback attractors for nonautonomous differential equations are investigated when the driving system of the generated skew-product flow is digitized.

Enriched (f, ϕ, ψ, s)‐Functional Contractions and Stability of Nonlinear Volterra Integral and Fractional Differential Equations

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this paper, we develop a comprehensive analytical framework for generalized nonlinear, nonhomogeneous Volterra integral equations and fractional differential equations in b‐metric spaces equipped with amorphous binary relations. By introducing an enriched (f, ϕ, ψ, s)‐functional contraction, we extend classical contractive conditions to accommodate ...

Upper semicontinuity of the attractor for lattice dynamical systems of partly dissipative reaction diffusion systems

Journal of Applied Mathematics, 2005
We investigate the existence of a global attractor and its upper semicontinuity for the infinite-dimensional lattice dynamical system of a partly dissipative reaction diffusion system in the Hilbert space l2×l2.

Existence and continuity of global attractors for a degenerate semilinear parabolic equation

Electronic Journal of Differential Equations, 2009
In this article, we study the existence and the upper semicontinuity with respect to the nonlinearity and the shape of the domain of global attractors for a semilinear degenerate parabolic equation involving the Grushin operator.

Semicontinuity of the Solution Mapping to a Parametric Generalized Weak Ky Fan Inequality

Abstract and Applied Analysis, 2014
Under new assumptions, which do not contain any information about the solution set, the upper and lower semicontinuity of the solution mapping to a class of parametric generalized weak Ky Fan inequality are established by using a nonlinear scalarization ...

Upper semicontinuity of uniform attractors for nonclassical diffusion equations

Boundary Value Problems, 2017
We study the upper semicontinuity of a uniform attractor for a nonautonomous nonclassical diffusion equation with critical nonlinearity. In particular, we prove that the uniform (with respect to (w.r.t.) g ∈ Σ $g\in \Sigma $ ) attractor A Σ ε $\mathcal ...

The Wu metric is not upper semicontinuous [PDF]

Proceedings of the American Mathematical Society, 2007
In this article a question asked in [\textit{M. Jarnicki} and \textit{P. Pflug}, Proc. Am. Math. Soc. 133, 239--244 (2005; Zbl 1051.32009)] is discussed, namely: Are the Wu metrics, associated to the Azukawa and the Kobayashi metric, respectively, upper semicontinuous?
