Title: Perturbations of bounce scenario from f(T) modified gravity revisited
Date: Thursday, January 30, 2020, 17:00-18:00
Venue: ES635

Abstract: In this talk, I will revisit the perturbations that are generated in the bounce scenario constructed within the framework of f(T) theory. I will show several conditions that f(T) bounce model must satisfy if it is going to avoid all the instabilities in any scales. By taking into account these conditions, we will show whether it is difficult or not to have bounce models within f(T) gravity, and how to get out of the possible difficulties.

The seminar is being held jointly by QG-Lab. and KMI.
