Holographic QFTs and effective de Sitter gravity theories

Abstract: Holographic theories can be defined on  curved space times and coupled to dynamical  boundary gravity by an appropriate renormalization procedure. In this talk,
I will discuss how  the coupling to a holographic QFTs affects gravitational dynamics  in de Sitter spacetime.
In particular, I will discuss the question  of  the spectrum
of graviton modes and the perturbative stability and consistency of the effective field theory of a CFT-gravity system.
