Conducive integral domains as pullbacks

Manuscripta Mathematica, 1986
A ''conducive domain'' is a (commutative unitary integral) domain R, with quotient field F, such that for every overring T of R, \(R\subseteq T\subsetneqq F\), the conductor \((R:T)=\{x\in F;\quad xT\subseteq R\}\) is nonzero [cf. \textit{E. Bastida} and \textit{R. Gilmer}, Mich. Math. J. 20, 79- 95 (1973; Zbl 0239.13001) and \textit{D. E.

Volume Quantization with Flexible Singularities for Hexahedral Meshing

Computer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

Dirac operator on spinors and diffeomorphisms

, 2012
The issue of general covariance of spinors and related objects is reconsidered. Given an oriented manifold $M$, to each spin structure $\sigma$ and Riemannian metric $g$ there is associated a space $S_{\sigma, g}$ of spinor fields on $M$ and a Hilbert ...

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 ...

New Results About Some Chain Conditions in Serre Conjecture Rings

Axioms
Let φ:T→T/I be the natural homomorphism, where I is a nonzero ideal of an integral domain T. We define R:=φ−1(D), where D is a subring of T/I. This paper aims to investigate the conditions under which the Serre conjecture ring R⟨m⟩ is a strong S-domain ...

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

The pullbacks of principal coactions

Documenta Mathematica, 2014
We prove that the class of principal coactions is closed under one-surjective pullbacks in an appropriate category of algebras equipped with left and right coactions. This allows us to handle cases of C^* -algebras lacking two different non-trivial ...

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

On the Dimension of the Pullback Attractors for g-Navier-Stokes Equations

Discrete Dynamics in Nature and Society, 2010
We consider the asymptotic behaviour of nonautonomous 2D g-Navier-Stokes equations in bounded domain Ω. Assuming that f∈Lloc2, which is translation bounded, the existence of the pullback attractor is proved in L2(Ω) and H1(Ω).

Coulomb branch algebras via symplectic cohomology

Journal of Topology, Volume 19, Issue 2, June 2026.
Abstract Let (M¯,ω)$(\bar{M}, \omega)$ be a compact symplectic manifold with convex boundary and c1(TM¯)=0$c_1(T\bar{M})=0$. Suppose that (M¯,ω)$(\bar{M}, \omega)$ is equipped with a convex Hamiltonian G$G$‐action for some connected, compact Lie group G$G$.
