"IR Issues in Inflation"

R. Holman

I review some recent work on the effects of infrared physics in de Sitter space, done in collaboration with Burgess, Shandera and Leblond. I''ll discuss the breakdown of the perturbative expansion due to these effects, as well as the use of the dynamical renormalization group to resum the secular terms that appear in field correlation functions. Time permitting, I''ll also talk about some new work in progress with Dan Boyanovsky regarding the stability of perturbative vacua in de Sitter.
