On blow-ups of sets with finite fractional variation

Giorgio Stefani

Given $α \in (0, 1)$ and a set $E \subset R^{N}$ with locally finite fractional $α$ -variation, we show that for $∣ D^{α} 1_{E} ∣$ -a.e. $x$ , every non-trivial tangent set of $E$ …

On a weighted version of the BBM formula

Giorgio Stefani

We prove a weighted version of the Bourgain-Brezis-Mironescu (BBM) formula, both in the pointwise and $Γ$ -convergence sense, together with a compactness criterion for energy-bounde…

On the Steiner property for planar minimizing clusters. The isotropic case

Valentina Franceschi, Aldo Pratelli, Giorgio Stefani

We consider the isoperimetric problem for clusters in the plane with a double density, that is, perimeter and volume depend on two weights. In this paper we consider the isotropic…
