Non-local functions and a denoising model with fidelity
Konstantinos Bessas, Giorgio Stefani
We study a general total variation denoising model with weighted fidelity, where the regularizing term is a non-local variation induced by a suitable (non-integrable) kernel…
The Cheeger problem in abstract measure spaces
Valentina Franceschi, Andrea Pinamonti, Giorgio Saracco +1
We consider non-negative -finite measure spaces coupled with a proper functional that plays the role of a perimeter. We introduce the Cheeger problem in this framework and e…
Failure of the local chain rule for the fractional variation
Giovanni E. Comi, Giorgio Stefani
We prove that the local version of the chain rule cannot hold for the fractional variation defined in arXiv:1809.08575. In the case , we prove a stronger result, exhibiting…
On Double Hölder Regularity of the Hydrodynamic Pressure in Bounded Domains
Luigi De Rosa, Mickaël Latocca, Giorgio Stefani
We prove that the hydrodynamic pressure associated to the velocity , , of an inviscid incompressible fluid in a bounded and simply connected domain $Ω\s…
Weak-strong uniqueness and vanishing viscosity for incompressible Euler equations in exponential spaces
Luigi De Rosa, Marco Inversi, Giorgio Stefani
In the class of admissible weak solutions, we prove a weak-strong uniqueness result for the incompressible Euler equations assuming that the symmetric part of the gradient belongs…
