Ghost Constraints on Modified Gravity
Alvaro Nunez, Slava Solganik
We show that general infrared modifications of the Einstein-Hilbert action obtained by addition of curvature invariants are not viable. These modifications contain either ghosts or…

Schwarzschild solution in brane induced gravity
Gregory Gabadadze, Alberto Iglesias
The metric of a Schwarzschild solution in brane induced gravity in five dimensions is studied. We find a nonperturbative solution for which an exact expression on the brane is obta…
