Ghost-free F(R,G) gravity
In this work we shall address the ghost issue of F(R,G) gravity, which is known to be plagued with ghost degrees of freedom. These ghosts occur due to the presence of higher than two derivatives in the field equations, and can arise even when considering cosmological perturbations, where superlumina...
