G‐Convergence of Friedrichs Systems Revisited

Mathematical Methods in the Applied Sciences, Volume 48, Issue 5, Page 6081-6091, 30 March 2025.
ABSTRACT We revisit the homogenization theory for Friedrichs systems. In particular, we show that G$$ G $$‐compactness can be obtained under severely weaker assumptions than in the original work of Burazin and Vrdoljak (2014). In this way, we extend the applicability of G$$ G $$‐compactness results for Friedrichs systems to equations that yield memory ...

Continuity of the solutions sets for parametric set optimization problems

Journal of Inequalities and Applications
The current study focuses on exploring the stability of solution sets pertaining to set optimization problems, particularly with regard to the set order relation outlined by Karaman et al. 2018.

Quasi-stability and continuity of attractors for nonlinear system of wave equations

Nonautonomous Dynamical Systems, 2021
In this paper, we study the long-time behavior of a nonlinear coupled system of wave equations with damping terms and subjected to small perturbations of autonomous external forces.

Upper semicontinuous decompositions of developable spaces [PDF]

Proceedings of the American Mathematical Society, 1965
Presented here are theorems concerning upper semicontinuous decompositions of developable spaces, topological in the sense that the common parts of intersecting domains (open sets) are open. Theorem 1 shows that, if the elements of such a decomposition do not have nonbicompact [I] intersections with the closures of their complements, the decomposition ...

Rectifiability, finite Hausdorff measure, and compactness for non‐minimizing Bernoulli free boundaries

Communications on Pure and Applied Mathematics, Volume 78, Issue 3, Page 545-591, March 2025.
Abstract While there are numerous results on minimizers or stable solutions of the Bernoulli problem proving regularity of the free boundary and analyzing singularities, much less is known about critical points of the corresponding energy. Saddle points of the energy (or of closely related energies) and solutions of the corresponding time‐dependent ...

Upper semicontinuity of attractors of non-autonomous dynamical systems for small perturbations

Electronic Journal of Differential Equations, 2002
We study the problem of upper semicontinuity of compact global attractors of non-autonomous dynamical systems for small perturbations. For the general nonautonomous dynamical systems, we give the conditions of upper semicontinuity of attractors for small

Existence of equilibria in persuasion games with costly information acquisition

International Journal of Economic Theory, Volume 21, Issue 1, Page 52-63, March 2025.
Abstract This paper studies public information disclosure in games with rationally inattentive players. We establish how the existence of an optimal sender's strategy depends on the nature of the receivers' information cost. When the receivers' cost is strongly Uniformly Posterior Separable (UPS), selecting the sender's most preferred equilibrium (SPE)

Cone Lattices of Upper Semicontinuous Functions [PDF]

Proceedings of the American Mathematical Society, 1982
Let X X be a compact metric space. A well-known theorem of M. H. Stone states that if Ω \Omega is a vector lattice of continuous functions on X X that separates points and contains a nonzero constant function, then the uniform closure of Ω \Omega is C ...

Shift orbits for elementary representations of Kronecker quivers

Journal of the London Mathematical Society, Volume 111, Issue 3, March 2025.
Abstract Let r∈N⩾3$r \in \mathbb {N}_{\geqslant 3}$. We denote by Kr$K_r$ the wild r$r$‐Kronecker quiver with r$r$ arrows γi:1⟶2$\gamma _i \colon 1 \longrightarrow 2$ and consider the action of the group Gr⊆Aut(Z2)$G_r \subseteq \operatorname{Aut}(\mathbb {Z}^2)$ generated by δ:Z2⟶Z2,(x,y)↦(y,x)$\delta \colon \mathbb {Z}^2 \longrightarrow \mathbb {Z}^2,

Semicontinuity of capacity under pointed intrinsic flat convergence [PDF]

arXiv, 2022
The concept of the capacity of a compact set in $\mathbb R^n$ generalizes readily to noncompact Riemannian manifolds and, with more substantial work, to metric spaces (where multiple natural definitions of capacity are possible). Motivated by analytic and geometric considerations, and in particular Jauregui's definition of capacity-volume mass and ...
