On the Center of Mass of Asymptotically Hyperbolic Initial Data Sets
We define the (total) center of mass for suitably asymptotically hyperbolic time-slices of asymptotically anti-de Sitter spacetimes in general relativity. We do so in analogy to the picture that has
Scalar Curvature and the Einstein Constraint Equations
We survey some results on scalar curvature and properties of solutions to the Einstein constraint equations. Topics include an extended discussion of asymptotically flat solutions to the constraint
The foliation of asymptotically hyperbolic manifolds by surfaces of constant mean curvature (including the evolution equations and estimates)
Abstract.The Hamiltonian formulation of the Einstein equations is achieved by means of a foliation of the background Lorentz Manifold. The usage of maximal surfaces is the frequently applied gauge
A note on center of mass
We will discuss existence of center of mass on asymptotically Schwarzschild manifold defined by Huisken-Yau and Corvino-Schoen. Conditions of existence and examples on non existence are given.
Large outlying stable constant mean curvature spheres in initial data sets
We give examples of asymptotically flat three-manifolds $$(M,g)$$(M,g) which admit arbitrarily large constant mean curvature spheres that are far away from the center of the manifold. This resolves a
Rigidity of Area-Minimizing Free Boundary Surfaces in Mean Convex Three-Manifolds
We prove a local splitting theorem for three-manifolds with mean convex boundary and scalar curvature bounded from below that contain certain locally area-minimizing free boundary surfaces. Our
Unique isoperimetric foliations of asymptotically flat manifolds in all dimensions
We describe explicitly the large volume isoperimetric regions of a natural class of asymptotically flat manifolds, in any dimension. These isoperimetric regions detect the mass and the center of mass
Large isoperimetric surfaces in initial data sets
We study the isoperimetric structure of asymptotically flat Riemannian 3-manifolds (M,g) that are C^0-asymptotic to Schwarzschild of mass m>0. Refining an argument due to H. Bray we obtain an
On the center of mass in general relativity
The classical notion of center of mass for an isolated system in general relativity is derived from the Hamiltonian formulation and represented by a flux integral at infinity. In contrast to mass and
Existence and uniqueness of constant mean curvature foliation of asymptotically hyperbolic 3-manifolds II
Abstract In a previous paper, the authors showed that metrics which are asymptotic to Anti-de Sitter-Schwarzschild metrics with positive mass admit a unique foliation by stable spheres with constant

Curvature estimates for minimal hypersurfaces
In [12] J. Simons initiated a study of minimal cones from a more differential geometric point of view than had previously been attempted. One of Simons' main results was an identity for the Laplacian
Coordinate invariance and energy expressions in general relativity
The invariance of various definitions proposed for the energy and momentum of the gravitational field is examined. We use the boundary conditions that ${g}_{\ensuremath{\mu}\ensuremath{\nu}}$
Parabolic methods for the construction of spacelike slices of prescribed mean curvature in cosmological spacetimes
Spacelike hypersurfaces of prescribed mean curvature in cosmological spacetimes are constructed as asymptotic limits of a geometric evolution equation. In particular, an alternative, constructive

Proof of the positive mass theorem. II
The positive mass theorem states that for a nontrivial isolated physical system, the total energy, which includes contributions from both matter and gravitation is positive. This assertion was

LetM be a space-time whose local mass density is non-negative everywhere. Then we prove that the total mass ofM as viewed from spatial infinity (the ADM mass) must be positive unlessM is the flat

The mass of an asymptotically flat manifold
We show that the mass of an asymptotically flat n-manifold is a geometric invariant. The proof is based on harmonic coordinates and, to develop a suitable existence theory, results about elliptic
