Abstract:

The least gradient problem (minimizing the BV norm with given boundary data) is known to be equivalent, in the plane, to the Beckmann minimal-flow problem with source and target measures located on the boundary of the domain. Motivated by this fact, we prove $L^p$ summability results for the solution of the Beckmann problem in this setting, which improve upon previous results where the measures were themselves supposed to be $L^p$. This provides results about the $W^{1,p}$ regularity of the solution of the least gradient problem in uniformly convex domains.
