MiS Preprint Repository
We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Some fine properties of currents and applications to distributional Jacobians
Camillo De LellisAbstract
We study fine properties of currents in the framework of geometric measure theory on metric spaces developed by Ambrosio and Kirchheim in [1] and we prove a rectifiability criterion for flat currents of finite mass. We apply these tools to study the structure of the dis-tributional Jacobians of functions in the space BnV, defined by Jerrard and Soner in [2]. We define the subspace of special functions of bounded higher variation and we prove a closure theorem.
