Cosmological Solution Moduli of Bigravity
Nejat Tevfik Yilmaz
We construct the complete set of metric-configuration solutions of the ghost-free massive bigravity for the scenario in which the g-metric is the Friedmann-Lemaitre-Robertson-Walke…
Decoupling Solution Moduli of Bigravity
Nejat Tevfik Yilmaz
A complete classification of exact solutions of ghost-free, massive bigravity is derived which enables the dynamical decoupling of the background, and the foreground metrics. The g…
Effective Matter Cosmologies of Massive Gravity: Physical Fluids
Nejat Tevfik Yilmaz
We derive new cosmological solutions of the ghost-free massive gravity with a general background metric in which the contribution of the mass sector to the metric one is modeled by…
Effective Matter Cosmologies of Massive Gravity I: Non-Physical Fluids
Nejat Tevfik Yilmaz
For the massive gravity, after decoupling from the metric equation we find a broad class of solutions of the Stuckelberg sector by solving the background metric in the presence of…
Effective Fluid FLRW Cosmologies of Minimal Massive Gravity
Nejat Tevfik Yilmaz
By using a solution ansatz we partially decouple the metric and the Stuckelberg sectors of the minimal massive gravity (MMGR). In this scheme for a diagonal physical metric we find…
