implies NTA for a class of variable coefficient elliptic operators
Steve Hofmann, José María Martell, Tatiana Toro
We consider a certain class of second order, variable coefficient divergence form elliptic operators, in a uniform domain with Ahlfors regular boundary, and we show that the $A…
Conical square functions for degenerate elliptic operators
Li Chen, José María Martell, Cruz Prisuelos-Arribas
The aim of this paper is to study the boundedness of different conical square functions that arise naturally from second order divergence form degenerate elliptic operators. More p…
The BMO-Dirichlet problem for elliptic systems in the upper-half space and quantitative characterizations of VMO
José María Martell, Dorina Mitrea, Irina Mitrea +1
We prove that for any homogeneous, second order, constant complex coefficient elliptic system , the Dirichlet problem in with boundary data in BMO is well-p…
Rectifiability, interior approximation and Harmonic Measure
Murat Akman, Simon Bortz, Steve Hofmann +1
We prove a structure theorem for any -rectifiable set , , satisfying a weak version of the lower ADR condition, and having locally finite $H^n…
