Set-Valued Symmetric Generalized Strong Vector Quasi-Equilibrium Problems with Variable Ordering Structures

Mathematics, 2020
In this paper, two types of set-valued symmetric generalized strong vector quasi-equilibrium problems with variable ordering structures are discussed.

A note on Laplacian bounds, deformation properties, and isoperimetric sets in metric measure spaces

Journal of the London Mathematical Society, Volume 112, Issue 5, November 2025.
Abstract In the setting of length PI spaces satisfying a suitable deformation property, it is known that each isoperimetric set has an open representative. In this paper, we construct an example of a length PI space (without the deformation property) where an isoperimetric set does not have any representative whose topological interior is nonempty ...

Upper semicontinuity of the lamination hull [PDF]

ESAIM: Control, Optimisation and Calculus of Variations, 2018
Let  K ⊆ ℝ2×2 be a compact set, let Krc be its rank-one convex hull, and let L (K) be its lamination convex hull. It is shown that the mapping K ↦ L̅(K̅) is not upper semicontinuous on the diagonal matrices in ℝ2×2, which was a problem left by Kolář. This is followed by an example of a 5-point set of 2 × 2 symmetric matrices with non-compact lamination

Polyhedral Convexity and the Existence of Approximate Equilibria in Discontinuous Games [PDF]

Radzik (1991) showed that two-player games on compact intervals of the real line have " { equilibria for all " > 0, provided that payo® functions are upper semicontinuous and strongly quasi-concave.

Screening for breakthroughs

Theoretical Economics, Volume 20, Issue 4, Page 1323-1365, November 2025.
How best to incentivize prompt disclosure? We study this question in a general model in which a technological breakthrough occurs at an uncertain time and is privately observed by an agent, and a principal must incentivize disclosure via her control of a payoff‐relevant physical allocation.

Characterization of upper semicontinuously integrable functions [PDF]

Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1995
AbstractWe show that for a Henstock-Kurzweil integrable functionffor every ∈ > 0 one can choose an upper semicontinuous gage function δ, used in the definition of the HK-integral if and only if |f| is bounded by a Baire 1 function. This answers a question raised by C. E. Weil.

Nonrecursive dynamic incentives: A rate of convergence approach

Theoretical Economics, Volume 20, Issue 4, Page 1461-1520, November 2025.
In repeated principal‐agent problems and games, more outcomes are implementable when performance signals are privately observed by a principal or mediator with commitment power than when the same signals are publicly observed and form the basis of a recursive equilibrium. We investigate the gains from nonrecursive equilibria (e.g., “review strategies”)

Super‐Nash Performance

International Economic Review, Volume 66, Issue 4, Page 1487-1503, October 2025.
ABSTRACT In this paper, I introduce a novel benchmark in games, super‐Nash performance, and a solution concept, optimin, whereby players maximize their minimal payoff under unilateral profitable deviations by other players. Optimin achieves super‐Nash performance in that, for every Nash equilibrium, there exists an optimin where each player not only ...

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.

The relative Hodge–Tate spectral sequence for rigid analytic spaces

Journal of the London Mathematical Society, Volume 112, Issue 4, October 2025.
Abstract We construct a relative Hodge–Tate spectral sequence for any smooth proper morphism of rigid analytic spaces over a perfectoid field extension of Qp$\mathbb {Q}_p$. To this end, we generalise Scholze's strategy in the absolute case by using smoothoid adic spaces.
