Lobachevsky holography in conformal Chern-Simons gravity
Mario Bertin, Sabine Ertl, Hossein Ghorbani +3
We propose Lobachevsky boundary conditions that lead to asymptotically H^2xR solutions. As an example we check their consistency in conformal Chern-Simons gravity. The canonical ch…
Canonical bifurcation in higher derivative, higher spin, theories
S. Deser, S. Ertl, D. Grumiller
We present a non-perturbative canonical analysis of the D=3 quadratic-curvature, yet ghost-free, model to exemplify a novel, "constraint bifurcation", effect. Consequences include…
Conformal Chern-Simons holography - lock, stock and barrel
Hamid Afshar, Branislav Cvetković, Sabine Ertl +2
We discuss a fine-tuning of rather generic three dimensional higher-curvature gravity actions that leads to gauge symmetry enhancement at the linearized level via partial masslessn…
Holograms of Conformal Chern-Simons Gravity
H. Afshar, B. Cvetkovic, S. Ertl +2
We show that conformal Chern-Simons gravity in three dimensions has various holographic descriptions. They depend on the boundary conditions on the conformal equivalence class and…
All stationary axi-symmetric local solutions of topologically massive gravity
Sabine Ertl, Daniel Grumiller, Niklas Johansson
We classify all stationary axi-symmetric solutions of topologically massive gravity into Einstein, Schrödinger, warped and generic solutions. We construct explicitly all local solu…
Erratum to `Instability in cosmological topologically massive gravity at the chiral point', arXiv:0805.2610
Sabine Ertl, Daniel Grumiller, Niklas Johansson
We correct a sign in the first variation of the on-shell action of cosmological topologically massive gravity at the chiral point and present the three equations affected by that s…
