The rise of a tensor instability in Eddington-inspired gravity [PDF]
Celia Escamilla-Rivera, Maximo Banados, Pedro G. FerreiraIn this work an extension to Eddington's gravitational action is analyzed. We consider the tensor perturbations of a FLRW space-time in the Eddington regime in where the tensor mode is linearly unstable deep and the resulting modifications to Einstein regime are quite strong.View original: http://arxiv.org/abs/1301.5264
