Description
We consider certain enlargement operations of sets which are related to the Nagel-Stein approach regions and the maximal functions. The capacity and the Hausdorff content of enlarged sets are estimated and their relationship is shown.These results are applied to the boundary behavior of harmonic functions in the upper half space.
