Conformal Kähler rigidity of Einstein four-manifolds

Giovanni Catino, Davide Dameno

For a compact, connected, oriented Einstein four-manifold, we prove that, if the largest eigenvalue of the self-dual Weyl curvature is everywhere simple, then, after at worst…

Quasilinear Liouville equation on manifolds with nonnegative Ricci curvature

Giovanni Catino, Dario Daniele Monticelli, Alberto Roncoroni

We prove rigidity and classification results for the quasilinear Liouville equation associated with the -Laplacian on complete noncompact Riemannian manifolds with nonnegative R…

Gradient estimates for the Green kernel under spectral Ricci bounds, and the stable Bernstein theorem in

Xavier Cabre, Giovanni Catino, Luciano Mari +2

We describe a method to prove new integral inequalities for stable minimal hypersurfaces in Euclidean space. As an application, we give a simple proof that complete, two sided, sta…

Criticality, splitting theorems under spectral Ricci bounds and the topology of stable minimal hypersurfaces

Giovanni Catino, Luciano Mari, Paolo Mastrolia +1

In this paper we prove general criticality criteria for operators on manifolds with more than one end, where bounds the Ricci curvature, and a related spectral splittin…

Rigidity of solutions to singular/degenerate semilinear critical equations

Giovanni Catino, Dario Daniele Monticelli, Alberto Roncoroni

This paper deals with singular/degenerate semilinear critical equations which arise as the Euler-Lagrange equation of Caffarelli-Kohn-Nirenberg inequalities in , with…

Bach-pinched metrics on closed manifolds

Letizia Branca, Giovanni Catino, Davide Dameno

Exploiting the deformation method introduced by Aubin in his seminal work to construct constant negative scalar curvature metrics, we show the existence, on every closed manifold o…
