Spaces of Besov-Sobolev type and a problem on nonlinear approximation

Óscar Domínguez, Andreas Seeger, Brian Street +2

We study fractional variants of the quasi-norms introduced by Brezis, Van Schaftingen, and Yung in the study of the Sobolev space $W ˙^{1, p}$ . The resulting spaces are identifie…

Sparse Brudnyi and John-Nirenberg Spaces

Óscar Domínguez, Mario Milman

A generalization of the theory of Y. Brudnyi \cite{yuri}, and A. and Y. Brudnyi \cite{BB20a}, \cite{BB20b}, is presented. Our construction connects Brudnyi's theory, which relies o…

On the $A_{\infty}$ condition for elliptic operators in 1-sided NTA domains satisfying the capacity density condition

Mingming Cao, Óscar Domínguez, José María Martell +1

Let $Ω \subset R^{n + 1}$ , $n \geq 2$ , be a 1-sided non-tangentially accessible domain (i.e., quantitatively open and path-connected) satisfiying the capacity density condition…
