Existence of uniform Temple charts and applications to null distance
Benjamin Meco, Anna Sakovich, Christina Sormani
In this paper, we prove that Temple's cylindrical future null coordinate charts can be constructed uniformly and we estimate the gradients of their optical functions. We then apply…
A definition of the mass aspect function for weakly regular asymptotically hyperbolic manifolds
Romain Gicquaud, Anna Sakovich
In contrast to the well-known and unambiguous notion of ADM mass for asymptotically Euclidean manifolds, the notion of mass for asymptotically hyperbolic manifolds admits several i…
The Null distance encodes causality
A. Sakovich, C. Sormani
A Lorentzian manifold endowed with a time function, , can be converted into a metric space using the null distance, , defined by Sormani and Vega. We show that if the…
The Jang equation and the positive mass theorem in the asymptotically hyperbolic setting
Anna Sakovich
We solve the Jang equation with respect to asymptotically hyperbolic "hyperboloidal" initial data. The results are applied to give a non-spinor proof of the positive mass theorem i…
On center of mass and foliations by constant spacetime mean curvature surfaces for isolated systems in General Relativity
Carla Cederbaum, Anna Sakovich
We propose a new foliation of asymptotically Euclidean initial data sets by 2-spheres of constant spacetime mean curvature (STCMC). The leaves of the foliation have the STCMC-prope…
Almost Rigidity of the Positive Mass Theorem for Asymptotically Hyperbolic Manifolds with Spherical Symmetry
A Sakovich, C Sormani
We use the notion of intrinsic flat distance to address the almost rigidity of the positive mass theorem for asymptotically hyperbolic manifolds. In particular, we prove that a seq…
