About the Lorentzian Yamabe problem [PDF]

open access: yesGeometriae Dedicata, 2014
We investigate the solutions to the Yamabe problem on globally hyperbolic spacetimes. On standard static spacetimes, we prove the existence of global solutions and show with the help of examples that uniqueness does not hold in general.

Existence result for the CR-Yamabe equation

open access: yesBruno Pini Mathematical Analysis Seminar, 2013
In this note we will prove that the CR-Yamabe equation has infinitely many changing-sign solutions. The problem is variational but the associated functional does not satisfy the Palais-Smale compactness condition; by mean of a suitable group action we ...

Volume comparison and the sigma_k-Yamabe problem

open access: yes, 2002
In this paper we study the problem of finding a conformal metric with the property that the k-th elementary symmetric polynomial of the eigenvalues of its Weyl-Schouten tensor is constant. A new conformal invariant involving maximal volumes is defined, and this invariant is then used in several cases to prove existence of a solution, and compactness of

On Gauss-Bonnet Curvatures

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The $(2k)$-th Gauss-Bonnet curvature is a generalization to higher dimensions of the $(2k)$-dimensional Gauss-Bonnet integrand, it coincides with the usual scalar curvature for $k = 1$.

On Yamabe's problem---by a modified direct method

open access: yesTohoku Mathematical Journal, 1982
In this article, the author gives a new proof of T. Aubin's result to the effect that the total scalar curvature functional achieves its infimum in a given conformal class of metrics provided this infimum is less than its value on the standard sphere. The method is more functional analytical in spirit than Aubin's.

Compactness of solutions to the Yamabe problem

open access: yesComptes Rendus. Mathématique, 2004
We establish compactness of solutions to the Yamabe problem on any smooth compact connected Riemannian manifold (not conformally diffeomorphic to standard spheres) of dimension n⩽7 as well as on any manifold of dimension n⩾8 under some additional hypothesis.
