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,

Regularity and structure of pullback attractors for reaction-diffusion type systems without uniqueness [PDF]
, 2016 In this paper, we study the pullback attractor for a general reaction-diffusion system for which the uniqueness of solutions is not assumed. We first establish some general results for a multi-valued dynamical system to have a bi-spatial pullback ...

H^2-boundedness of the pullback attractor for the non-autonomous SIR equations with diffusion
, 2015 We prove some regularity results for the pullback attractor of a non- autonomous SIR model with diffusion in a bounded domain Ω of Rd where d ≥ 1. We show a regularity result for the unique solution of the prob- lem.

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

Pullback attractors for non-autonomous 2D-Navier-Stokes equations in some unbounded domains [PDF]
, 2006 In this Note we first introduce the concept of pullback asymptotic compactness. Next, we establish a result ensuring the existence of a pullback attractor for a non-autonomous dynamical system under the general assumptions of pullback asymptotic ...

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

Advances in Difference Equations, 2020 This paper is concerned with the asymptotic behavior of solutions to a non-autonomous stochastic wave equation with additive white noise, for which the nonlinear damping has a critical cubic growth rate.

On the Quot scheme QuotSl(E)$\mathrm{Quot}^{l}_{\mathrm{S}}(\mathcal {E})$
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract We study the geometry of the Quot scheme QuotSl(E)$\operatorname{Quot}^{l}_{\mathrm{S}}(\mathcal {E})$ of length l$l$ coherent sheaf quotients of a locally free sheaf E$\mathcal {E}$ on a smooth projective surface S$\mathrm{S}$. In particular, we investigate the nature of its singularities, its intersection theory, and the cohomology of ...

Pullback attractors for a singularly nonautonomous plate equation
Electronic Journal of Differential Equations, 2010 We consider the family of singularly nonautonomous plate equation with structural damping \[ u_{tt} + a(t,x)u_{t} + (- Δ) u_{t} + (-Δ)^{2} u + λu = f(u), \] in a bounded domain $Ω\subset \R^n$, with Navier boundary conditions. When the nonlinearity $f$ is dissipative we show that this problem is globally well posed in $H^2_0(Ω) \times L^2(Ω)$ and has a
