Nonderivative Modified Gravity: a Classification
Denis Comelli, Fabrizio Nesti, Luigi Pilo
We analyze the theories of gravity modified by a generic nonderivative potential built from the metric, under the minimal requirement of unbroken spatial rotations. Using the canon…

FRW Cosmological Perturbations in Massive Bigravity
D. Comelli, M. Crisostomi, L. Pilo
Cosmological perturbations of FRW solutions in ghost free massive bigravity, including also a second matter sector, are studied in detail. At early time, we find that sub horizon e…
