A new variational characterization of compact conformally flat 4-manifolds
Faen Wu, Xinnuan Zhao (2012)
Communications in Mathematics
In this paper, we give a new variational characterization of certain 4-manifolds. More precisely, let and denote the scalar curvature and Ricci curvature respectively of a Riemannian metric, we prove that if is compact and locally conformally flat and is the critical point of the functional where

A nonlinear Poisson transform for Einstein metrics on product spaces
Olivier Biquard, Rafe Mazzeo (2011)
Journal of the European Mathematical Society
We consider the Einstein deformations of the reducible rank two symmetric spaces of noncompact type. If is the product of any two real, complex, quaternionic or octonionic hyperbolic spaces, we prove that the family of nearby Einstein metrics is parametrized by certain new geometric structures on the Furstenberg boundary of .
