Concentration phenomena and the Vanishing Mass Conjecture
Luca Gennaioli, Filip Rindler
Concentrating (that is, non-equi-integrable) sequences of functions satisfying linear PDE constraints arise in a wide variety of problems in PDE, the calculus of variations, and ge…
Lipschitz continuity of harmonic maps between spaces and spaces
Luca Gennaioli
The paper proves that energy‑minimizing harmonic maps from a domain in an RCD(K,N) space into a sufficiently small ball of a CAT(κ) space are locally Lipschitz continuous, completi…
Sets of finite perimeter on Riemannian manifolds and stochastic completeness
Luca Gennaioli
We prove a heat semigroup characterization of the total variation for compactly supported on arbitrary smooth complete weighted Riemannian manifolds, extending the main…
A new Duhamel-type principle with applications to geometric (in)equalities
Michele Caselli, Luca Gennaioli
We introduce a simple new method, based on the Caffarelli-Silvestre extension and a Duhamel-type formula, to derive exact pointwise identities for fractional commutators and nonlin…
Sharp conditions for the BBM formula and asymptotics of heat content-type energies
Luca Gennaioli, Giorgio Stefani
Given , we provide sufficient and necessary conditions on the non-negative measurable kernels ensuring convergence of the associated Bourgain-B…
Fourier transform of BV functions and applications
Thomas Beretti, Luca Gennaioli
This paper investigates the relation between the Fourier transform of {\rm BV} (bounded variation) functions and their jump sets. We introduce the notion of -jump product and…
