Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Lifting in Sobolev spaces [PDF]

open access: greenJournal d'Analyse Mathématique, 2000
We characterize the couples $(s,p)$ with the following property: if $u$ is a complex-valued unimodular map in $W^{s,p}$, then $u$ has (locally) a phase in $W^{s,p}$.

Topology and Sobolev Spaces [PDF]

open access: bronzeJournal of Functional Analysis, 2001
Let two compact connected oriented smooth Riemannian manifolds \(M\) and \(N\) (with or without boundary) be given. It is supposed that \(\dim M\geq 2\); the example \(N=S^1\) is of importance. Let \(W^{1,p}(M,N)\) be the Sobolev space of functions \(u\in W^{1,p} (M,\mathbb{R}^k)\) with \(u(x)\in N\) a.e.

On anisotropic Sobolev spaces [PDF]

open access: yesCommunications in Contemporary Mathematics, 2019
We investigate two types of characterizations for anisotropic Sobolev and BV spaces. In particular, we establish anisotropic versions of the Bourgain–Brezis–Mironescu formula, including the magnetic case both for Sobolev and BV functions.

On fractional Orlicz–Sobolev spaces [PDF]

open access: yesAnalysis and Mathematical Physics, 2021
AbstractSome recent results on the theory of fractional Orlicz–Sobolev spaces are surveyed. They concern Sobolev type embeddings for these spaces with an optimal Orlicz target, related Hardy type inequalities, and criteria for compact embeddings.

Existence of Sobolev regular solutions for the incompressible flow of liquid crystals in three dimensions

open access: yesAIMS Mathematics, 2022
This paper considers a simplified three dimensional Ericksen-Leslie System for nematic liquid crystal flows in the unbounded domain $ \Omega: = \mathbb R^+\times \mathbb R^2 $ or the smooth bounded domain $ \Omega $.
