Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Regularity and Exponential Growth of Pullback Attractors for Semilinear Parabolic Equations Involving the Grushin Operator

Abstract and Applied Analysis, 2012
Considered here is the first initial boundary value problem for a semilinear degenerate parabolic equation involving the Grushin operator in a bounded domain Ω.

Weak upper semicontinuity of pullback attractors for nonautonomous reaction-diffusion equations

Electronic Journal of Qualitative Theory of Differential Equations, 2019
We consider nonautonomous reaction-diffusion equations with variable exponents and large diffusion and we prove continuity of the flow and weak upper semicontinuity of a family of pullback attractors when the exponents go to $2$ in $L^\infty(\Omega)$.

Pullback Attractors for a Class of Semilinear Second-Order Nonautonomous Evolution Equations with Hereditary Characteristics

Journal of Mathematics, 2022
In this paper, we investigate the long-time behavior for the nonautonomous semilinear second-order evolution equation ∂2u/∂t2−Δu−Δ∂u/∂t−Δ∂2u/∂t2=ft,ux,t−ρt+gt,x,inτ,∞×Ω with some hereditary characteristics, where Ω is an open-bounded domain of ℝNN≥3 with

Signals, Red Lines, and Collision: The Israel‐Iran Spiral and US Intervention

Middle East Policy, Volume 33, Issue 2, Page 5-23, Summer 2026.
Abstract The Iran War erupted in February 2026 without UN authorization, and Washington's rationales—Iranian nuclear ambitions, missile capacity, and proxy threats—map more closely onto Israeli than US security interests. Why have we seen two major conflicts between these belligerents in less than one year?

Pullback attractors for a class of non-Newtonian micropolar fluids

Electronic Journal of Differential Equations, 2018
In this article we study the long time behavior of the two-dimensional flow for non-Newtonian micropolar fluids in bounded smooth domains, in the sense of pullback attractors.

Trump's Transactional Diplomacy: Breakthrough or Breakdown?

Middle East Policy, Volume 33, Issue 2, Page 24-40, Summer 2026.
Abstract The US‐Israeli war on Iran appears to demonstrate the perils of a transactional diplomacy that dismisses the rules‐based, liberal international order in pursuit of American dominance. Much of the growing literature assumes transactional diplomacy will be a temporary, Trump‐driven departure from traditional, values‐based statecraft. By contrast,

Selective Convergence of Followers to Multiple Leaders With Repulsion and Cohesion on Riemannian Manifolds

Studies in Applied Mathematics, Volume 156, Issue 6, June 2026.
ABSTRACT We study the long‐term dynamics of followers that selectively follow one of multiple leaders on Riemannian manifolds, where the leaders interact through repulsive forces while remaining cohesively bounded. We propose a multileader–follower multiagent system defined on Riemannian manifolds. In our model, each follower chooses exactly one leader

Asylum as Artifice: Race, Law and Capital as Regimes of Abstraction in the United Kingdom's Asylum Accommodation System

Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
ABSTRACT Taking as its case study the category of the ‘asylum seeker’ in UK law, this paper develops on latent concerns in legal geographies with processes of abstraction. Following Bhandar and Toscano, race, law and capital are here understood as different, co‐articulating modalities of abstraction, through which the ‘asylum seeker’ is constituted and

Pullback measure attractors and evolution system of measures for p-Laplacian Ginzburg–Landau lattice systems driven by superlinear Lévy noise

Advanced Nonlinear Studies
This paper investigates the existence, uniqueness, and asymptotic behavior of pullback measure attractors and evolution systems of measures for a complex-valued p-Laplacian Ginzburg–Landau lattice system (GLLS) driven by superlinear Lévy noise.
