Quantization for Palais-Smale sequences of the Liouville functional on closed surfaces

Andrea Malchiodi, Francesco Malizia, Luca Martinazzi

In this paper we prove a quantization property for Palais-Smale sequences of functionals related to Liouville equations on compact surfaces. While these equations have been extensi…

Decreasing Weyl's energy by connected sums with locally conformally flat manifolds

Andrea Malchiodi, Francesco Malizia

We study the Weyl functional on connected sums of two four-dimensional manifolds $(M, g_{M})$ and $(Z, g_{Z})$ , assuming $g_{M}$ is Bach-flat and $g_{Z}$ locally conformally flat. We show th…

Min-max theory and Yamabe metrics on conical four-manifolds

Mattia Freguglia, Andrea Malchiodi, Francesco Malizia

We prove existence of Yamabe metrics on four-manifolds possessing finitely-many conical points with $Z_{2}$ -group, using for the first time a min-max scheme in the singular…

Weyl energy and connected sums of four-manifolds

Andrea Malchiodi, Francesco Malizia

Given two closed, oriented Riemannian four-manifolds $(M, g_{M})$ and $(Z, g_{Z})$ , which are not locally conformally flat and not both self-dual or both anti-self-dual, we prove that th…

Yamabe metrics on conical manifolds

Mattia Freguglia, Andrea Malchiodi

We prove existence of Yamabe metrics on singular manifolds with conical points and conical links of Einstein type that include orbifold structures. We deal with metrics of generic…
