The Besov Capacity In Metric Spaces

Functional Analysis 2016-08-03 v2

Abstract

We study a capacity theory based on a definition of Haj{\l} asz-Besov functions. We prove several properties of this capacity in the general setting of a metric space equipped with a doubling measure. The main results of the paper are lower bound and upper bound estimates for the capacity in terms of a modified Netrusov-Hausdorff content. Important tools are γ\gamma-medians, for which we also prove a new version of a Poincar\'e type inequality.
