Anosov representations as holonomies of globally hyperbolic spatially compact conformally flat spacetimes
Rym Smai
Anosov representations were introduced by F. Labourie [18] for fundamental groups of closed negatively curved surfaces, and generalized by O. Guichard and A. Wienhard [19] to repre…
Quasi-Fuchsian co-Minkowski manifolds
Thierry Barbot, François Fillastre
This survey is an introduction to the geometry of co-Minkowksi space, the space of unoriented spacelike hyperplanes of the Minkowski space. Affine deformations of cocompact lattice…
On the irreducible action of psl(2, r) on the 3-dimensional einstein universe
Masoud Hassani
We describe the orbits of the irreducible action of PSL(2, R) on the 3-dimensional Einstein universe Ein 1,2. This work completes the study in [2], and is one element of the classi…
Inversion of some curvature operators near a parallel Ricci metric II: Non-compact manifold with bounded geometry
Erwann Delay
Let (M,g) be a complete noncompact riemannian manifold with bounded geometry and parallel Ricci curvature. We show that some operators, "affine" relatively to the Ricci curvature,…
Lp almost conformal isometries of Sub-Semi-Riemannian metrics and solvability of a Ricci equation
Erwann Delay
Let M be a smooth compact manifold without boundary. We consider two smooth Sub-Semi-Riemannian metrics on M. Under suitable conditions, we show that they are almost conformally is…
Hilbert manifold structure for asymptotically hyperbolic relativistic initial data
Erwann Delay, Jérémie Fougeirol
We provide a Hilbert manifold structure {à} la Bartnik for the space of asymptotically hyperbolic initial data for the vacuum constraint equations. The adaptation led us to prove n…
