Abstract: Rigging technique introduced in Gutiérrez and Olea (Math Nachr 289:1219–1236, 2016) is a convenient way to address the study of null hypersurfaces. It offers, in addition, the extra benefit of inducing a Riemannian structure on… read more here.

Published in 2022 at "Communications in Mathematical Physics"

DOI: 10.1007/s00220-022-04326-9

Abstract: We study the mean curvature flow in 3-dimensional null hypersurfaces. In a spacetime a hypersurface is called null, if its induced metric is degenerate. The speed of the mean curvature flow of spacelike surfaces in… read more here.

DOI: 10.1088/1361-6382/ae22b5

Abstract: We study null hypersurfaces approaching null infinity in asymptotically flat spacetimes within the Bondi–Sachs gauge. The null Raychaudhuri constraint is shown to asymptote to the Bondi mass-loss formula, interpreted as a stress tensor conservation law.… read more here.
