This requires identifying a gravitational metric and parameterizing deviations of the resulting theory from general relativity. To this end, we first consider the most general bimetric backgrounds for ... chiptuning fiat

WebMar 31, 2014 · We study cosmological perturbations in bimetric theory with two fluids each of which is coupled to one of the two metrics. Focusing on a healthy branch of background solutions, we clarify the stability of the cosmological perturbations. For this purpose, we extend the condition for the absence of the so-called Higuchi ghost, and show that the … WebMar 28, 2024 · In this paper we consider a specific type of the bimetric theory of gravitation with the two different metrics introduced in the cosmological frame. Both metrics respect all the symmetries of the standard FLRW solution and contain conformally related spatial parts. One of the metric is assumed to describe the causal structure for the matter.

WebThis e ective theory is geometric in nature, covariant with respect to spatial dif-feomorphisms, and nonlinear by construction. Similarly to Ref. [26], the theory consists of a Chern-Simons TQFT interacting with a massive spin-2 eld, whose dynamics is governed by an action reminiscent of the action for bimetric theory of massive gravity. WebIntroduction to Bimetric Theory We begin this chapter by recalling some ideas from General Relativity(GR). We then introduce a linear theory of massive gravity, the Fierz-Pauli theory and explain issues faced by it and similar theories before introducing the ghost free bimetric theory which was rst introduced by Hassan and Rosen in 2011 [1] [2].
