Pullback attractor of a non-autonomous order-2γ parabolic equation for an epitaxial thin film growth model

Boundary Value Problems, 2020
The non-autonomous order-2γ parabolic partial differential equation for an epitaxial thin film growth model with dimension d = 3 $d=3$ is investigated by the method of uniform estimates.

Structural change in the US office market after 2019: Evidence from lease‐level data

Real Estate Economics, EarlyView.
Abstract This article examines how the leasing activities, contract features, and pricing of the Class A office leasing market have evolved since 2019 across five major US markets: Los Angeles, the Bay Area, Dallas, Washington, DC, and New York City. Using a granular dataset of 73,508 office leases from 2010 to 2024, we find a broad‐based contraction ...

Establishing Shape Correspondences: A Survey

Computer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Does the US Cross‐Listing of a Non‐US Stock Influence the Impact of Economic Policy Uncertainty on Stock Liquidity?

Financial Management, EarlyView.
ABSTRACT We examine how US cross‑listing shapes the sensitivity of non‑US firms’ home‑market liquidity to economic policy uncertainty (EPU). Using a matched global panel of 1894 American Depositary Receipts (ADRs) and comparable non‐cross‑listed firms from 20 countries between 1997 and 2024, we separately identify the effects of home‑country EPU and US

Minimality Properties of Set-Valued Processes and their Pullback Attractors [PDF]

SIAM Journal on Mathematical Analysis, 2015
We discuss the existence of pullback attractors for multivalued dynamical systems on metric spaces. Such attractors are shown to exist without any assumptions in terms of continuity of the solution maps, based only on minimality properties with respect to the notion of pullback attraction. When invariance is required, a very weak closed graph condition

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 ...

Upper semicontinuity of pullback attractors for a nonautonomous damped wave equation

Boundary Value Problems, 2021
In this paper, we study the local uniformly upper semicontinuity of pullback attractors for a strongly damped wave equation. In particular, under some proper assumptions, we prove that the pullback attractor { A ε ( t ) } t ∈ R $\{A_{\varepsilon }(t)\}_ ...

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 to impulsive evolution processes: Applications to differential equations and tube conditions

, 2020
We define the notions of impulsive evolution processes and their pullback attractors, and exhibit conditions under which a given impulsive evolution process has a pullback attractor.
