A new characterization of Sobolev spaces on
Roc Alabern, Joan Mateu, Joan Verdera
In this paper we present a new characterization of Sobolev spaces on Euclidian spaces (). Our characterizing condition is obtained via a quadratic multiscale expressi…

Capacities associated with scalar signed Riesz kernels, and analytic capacity
Joan Mateu, Laura Prat, Joan Verdera
The real and imaginari parts of the Cauchy kernel in the plane are scalar Riesz kernels of homogeneity -1. One can associate with each of them a natural notion of capacity related…

Quasiconformal distortion of Riesz capacities and Hausdorff measures in the plane
K. Astala, A. Clop, X. Tolsa +2
In this paper we prove the sharp distortion estimates for the quasiconformal mappings in the plane, both in terms of the Riesz capacities from non linear potential theory and in te…
