Cosmological perturbations and the stability of de Sitter


Abstract:


Inflation together with cosmological perturbation theory is very successful in explaining the origin of structure and the CMB anisotropies. However, at higher orders there are notorious infrared issues plaguing perturbation theory in inflationary (quasi) de Sitter space-times. We will discuss what we can learn about the stability of de Sitter from non-linear cosmological perturbations and the other way around.
