Stability of the Minkowski spacetime in Newman-Unti gauge
Jonathan Luk, Sung-Jin Oh, Claude Warnick
We prove small-data global stability of the Minkowski solution to Einstein's equations in a centre-normalised outgoing null-geodesic gauge. Our scheme involves first using the $r^p…

The formation of a weak null singularity in the interior of generic rotating black holes
Jonathan Luk, Jan Sbierski
Given a characteristic initial value problem with smooth data representing a dynamical event horizon settling down to that of Kerr in the subextremal, strictly rotating range with…

Late time tail of waves on dynamic asymptotically flat spacetimes of odd space dimensions
Jonathan Luk, Sung-Jin Oh
We introduce a general method for understanding the late time tail for solutions to wave equations on asymptotically flat spacetimes with odd space dimensions. In particular, for a…
