Sala Seminari, Department of Mathematics, Pisa University
The first part of this seminar will be concerned with an issue of strict interior approximation for sets of finite perimeter and functions of bounded variation. Then, I will turn to extremality relations between BV-minimizers of variational integrals and dual solutions in the sense of convex analysis. Finally, I am planning to make connections to uniqueness and regularity results for these minimizers. The presented results are based on joint works with Lisa Beck.
