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 ...

Random dynamics of fractional stochastic retarded FitzHugh–Nagumo systems on unbounded domains

Journal of Inequalities and Applications
In this paper, we study the dynamics of fractional nonautonomous stochastic FitzHugh–Nagumo systems with variable delay defined on R n $\mathbb{R}^{n}$ .

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 $L^\infty(\Omega)$.

Random attractors for stochastic evolution equations driven by fractional Brownian motion [PDF]

, 2013
The main goal of this article is to prove the existence of a random attractor for a stochastic evolution equation driven by a fractional Brownian motion with $H\in (1/2,1)$.

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

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

Attractors for Differential Equations with Multiple Variable Delays [PDF]

, 2009
We establish some results on the existence of pullback attractors for non-autonomous delay di fferential equations with multiple delays. In particular, we generalise some recent works on the existence of pullback attractors for delay di fferential ...

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, EarlyView.
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 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 ...
