Self-accelerating Massive Gravity: Bimetric Determinant Singularities
Pierre Gratia, Wayne Hu, Mark Wyman
The existence of two metrics in massive gravity theories in principle allows solutions where there are singularities in new scalar invariants jointly constructed from them. These c…

Self-accelerating Massive Gravity: How Zweibeins Walk through Determinant Singularities
Pierre Gratia, Wayne Hu, Mark Wyman
The theory of massive gravity possesses ambiguities when the spacetime metric evolves far from the non-dynamical fiducial metric used to define it. We explicitly construct a spheri…
