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].
