SEMINAR: On the non-linear scale of cosmological perturbation theory

Thursday March 20 2014, 2:40pm - Seminar room

Speaker: Thomas Konstandin (DESY)

Abstract:

I discuss the use of perturbative methods to study the evolution of matter fluctuations in the context of large scale structure formation.

After an extensive introduction, I compare a couple of recently developed techniques in perturbation theory as renormalized perturbation theory, the eikonal approximation and Pade resummation.
