Hausdorff dimension of removable sets for elliptic and canceling homogeneous differential operators in the class of bounded functions

Abstract

In this note we give an upper bound on the Hausdorff dimension of removable setsfor elliptic and canceling homogeneous differential operators with constant coefficients in the class of bounded functions, using a simple extension of Frostman's lemma in Euclidean space with an additional power decay.
