Abstract:
We prove a Sobolev type inequality for functions which partial derivatives in the sense of distribution have total variation in some amalgam space of measures.The proof is based on a trace theorem for Riesz potentials of Radon measures written in the form of an Olsen type inequality. We use this Sobolev inequality to obtain regularity conditions for solution of
where the data is a nonnegative Radon measure.
