From Einstein through Vainshtein to dRGT design

Lavinia Heisenberg


Recently there has been a successful non-linear covariant ghost-free generalization of Fierz-Pauli massive gravity theory, the dRGT theory. I will explore the cosmology in the decoupling limit of this theory. Furthermore, I will discuss a Proxy to dRGT and study the cosmology there as well and compare the results.
