Speaker: Martin S. Sloth

Title:
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.
