This authoritative book presents recent research results on nonlinear problems with lack of
compactness. The topics covered include several nonlinear problems in the Euclidean …

In this paper we study the Palais–Smale sequences of the conformal Dirac–Einstein
problem. After we characterize the bubbling phenomena, we prove an Aubin type result …

In this paper, we construct a Rabinowitz–Floer type homology for a class of non-linear
problems having a starshaped potential; we consider some equivariant cases as well. We …

In this paper we consider the functional whose critical points are solutions of the fractional
CR Yamabe type equation on the sphere. We firstly study the behaviour of the Palais–Smale …

On a closed balanced manifold, we show that if the Chern scalar curvature is small enough
in a certain Sobolev norm, then a slightly modified version of the Chern–Yamabe flow …

We prove that the fractional Yamabe equation. Our argument is variational, based on a Ding-
type conformal pulling-back transformation of the original problem into a problem on the CR …
