Stratification of the single blow-up set for Radon measures

Luigi De Masi

We show that the set of points where the blow-up, in the sense of Preiss, of a signed Radon measure on $R^{n}$ is unique and its invariant subspace has dimension $k$ is $k$ -…

Lipschitz solvability of prescribed Jacobian and divergence for singular measures

Luigi De Masi, Andrea Marchese

Let $I^¼$ be a finite Radon measure on an open set $I^c ◯ \subset R^{d}$ , singular with respect to the Lebesgue measure. We prove Lusin-type solvability results for the prescribed…

Non-rigidity of the absolutely continuous part of $A$ -free measures

Luigi De Masi, Carlo Gasparetto

We generalize a result by Alberti, showing that, if a first-order linear differential operator $A$ belongs to a certain class, then any $L^{1}$ function is the absolutely c…
