Optimal Poisson kernel regularity for elliptic operators with Hölder-continuous coefficients in vanishing chord-arc domains
Simon Bortz, Tatiana Toro, Zihui Zhao
We show that if is a vanishing chord-arc domain and is a divergence-form elliptic operator with Hölder-continuous coefficient matrix, then , where i…

Coronizations and big pieces in metric spaces
Simon Bortz, John Hoffman, Steve Hofmann +2
We prove that coronizations with respect to arbitrary d-regular sets (not necessarily graphs) imply big pieces squared of these (approximating) sets. This is known (and due to Davi…

Critical Perturbations for Second Order Elliptic Operators. Part I: Square function bounds for layer potentials
Simon Bortz, Steve Hofmann, José Luis Luna Garcia +2
This is the first part of a series of two papers where we study perturbations of divergence form second order elliptic operators by first an…
