Add to ORKGThese notes stem from some talks we gave at the Institut Fourier of Grenoble in 1998, where we compared Besson-Courtois-Gallot’s and Lebrun’s approaches to uniqueness of Einstein metrics on real and complex hyperbolic 4-manifolds. The Ricci tensor of a Riemannian manifold (X, g) is the symmetric bilinear form define
