Abstract:
We consider the minimization problem for an average distance functional in the plane, among all compact connected sets of prescribed length, as proposed by Buttazzo, Oudet and Stepanov. For a minimizing set, the blow-up sequence in the neighbourhood of any point is investigated. We show existence of the blow up limits and we characterize them, using the results to get some partial regularity statements. In particular we get $C^{1,1}$ regularity near triple junctions.
