Spacetime Bartnik Mass Positivity and Temporal Monotonicity for Black Holes

Lars Andersson, Marcus Khuri, Marc Mars +1

We define a quasilocal mass of Bartnik type, and establish its positivity and temporal monotonicity properties for two classes of domains associated with black holes. More precisel…

Transverse expansion of the metric at null infinity

Marc Mars, Gabriel Sánchez-Pérez

In this paper we analyze the conformal Einstein equations to all orders at null infinity without imposing any restriction on the spacetime dimension, the topology of ,…

Horizon Data: Existence Results and a Near-Horizon Equation on General Null Hypersurfaces

Miguel Manzano, Marc Mars

In a spacetime , a horizon is a null hypersurface where the deformation tensor of a null and tangent vector satisfies certain restrictions.…

Conformal characterization of the Fefferman-Graham ambient metric

Marc Mars, Gabriel Sánchez-Pérez

In this paper, we study the asymptotic structure of the Fefferman-Graham ambient metric. We prove that every straight ambient metric admits a conformal completion with a well-defin…

Killing and homothetic initial data for general hypersurfaces

Marc Mars, Gabriel Sánchez-Pérez

In this paper we present a collection of general identities relating the deformation tensor of an arbitrary vector field with the tensor $Σ=\mathca…

Transverse expansion of the metric at null hypersurfaces II. Existence results and application to Killing horizons

Marc Mars, Gabriel Sánchez-Pérez

This paper finishes the series of two papers that we started with [arXiv:2405.05377], where we analyzed the transverse expansion of the metric at a general null hypersurface. While…
