Problems of Massive Gravities
S. Deser, K. Izumi, Y. C. Ong +1
The method of characteristics is a key tool for studying consistency of equations of motion; it allows issues such as predictability, maximal propagation speed, superluminality, un…
Superluminal Propagation and Acausality of Nonlinear Massive Gravity
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity is an old idea: trading geometry for mass. Much effort has been expended on establishing a healthy model, culminating in the current ghost-free version. We summariz…
Massive Gravity Acausality Redux
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity (mGR) is a 5(=2s+1) degree of freedom, finite range extension of GR. However, amongst other problems, it is plagued by superluminal propagation, first uncovered via…
No consistent bimetric gravity?
S. Deser, M. Sandora, A. Waldron
We discuss the prospects for a consistent, nonlinear, partially massless (PM), gauge symmetry of bimetric gravity (BMG). Just as for single metric massive gravity, we show that con…
Nonlinear Partially Massless from Massive Gravity?
S. Deser, M. Sandora, A. Waldron
We show that consistent nonlinear Partially Massless models cannot be obtained starting from "f-g" massive gravity, with "f" the embedding de Sitter space. The obstruction, which i…
PM = EM: Partially Massless Duality Invariance
S. Deser, A. Waldron
In d=4 de Sitter space, novel conformally invariant photon-like theories consistently couple to charged matter. We show that these higher spin, maximal depth, partially massless sy…
