Quasilinear reformulation of Lovelock gravity
Steven Willison
Here we give an extended review of the quasilinear reformulation of the Lovelock gravitational field equations in harmonic gauge presented in 1409.6656 [gr-qc]. This is important i…
Local Well-posedness of Lovelock gravity
Steven Willison
It has long been known that Lovelock gravity, being of Cauchy-Kowalevskaya type, admits a well defined initial value problem for analytic data. However, this does not address the p…
A Re-examination of the isometric embedding approach to General Relativity
Steven Willison
We consider gravitational field equations which are Einstein equations written in terms of embedding coordinates in some higher dimensional Minkowski space. Our main focus is to ad…
AdS spacetimes and isometric embeddings
Steven Willison
An algebraic global isometric embedding of the nonrotating BTZ black hole is presented. The ambient spacetime is , the 3+2 dimensional flat spacetime. We also pre…
Gauged WZW models for space-time groups and gravitational actions
Pablo Mora, Pablo Pais, Steven Willison
In this paper we investigate gauged Wess-Zumino-Witten models for space-time groups as gravitational theories, following the trend of recent work by Anabalon, Willison and Zanelli.…
Lovelock black holes with maximally symmetric horizons
Hideki Maeda, Steven Willison, Sourya Ray
We investigate some properties of n(\ge 4)-dimensional spacetimes having symmetries corresponding to the isometries of an (n-2)-dimensional maximally symmetric space in Lovelock gr…
