Bartnik Hilbert manifold structure on fibers of the scalar curvature and the constraint operator

Erwann Delay

We adapt the Bartnik method to provide a Hilbert manifold structure for the space of solutions, without KID's, to the vacuum constraint equations on compact manifold of any dimensi…

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…

Conformally covariant parametrizations for initial data in some modified Einstein gravity theories

Erwann Delay

We propose further conformal parametrizations for initial data in some modified Einstein gravity theories. Some of them give rise to conformally covariant systems.

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…
