DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CCTP_HEP/53/
 ">Holographic cosmology and the origin of time</a>\nby Kostas Skenderis (S
 outhampton) as part of CCTP HEP Seminars\n\n\nAbstract\nHolographic cosmol
 ogy is a new framework for the very early universe\, the period usually as
 sociated with inflation. In holographic cosmology the early Universe is de
 scribed by a three dimensional QFT\, and cosmological evolution is mapped 
 to inverse RG flow. In this talk\, I will provide an overview of holograph
 ic cosmology and then discuss recent work where lattice QFT methods are us
 ed to compute the relevant QFT observables. In particular\, I will discuss
  the IR structure of the dual QFT\, which is linked to the initial singula
 rity in cosmology\, and show how non-perturbative dynamics resolve the IR 
 singularities present in perturbation theory\, thus providing a holographi
 c resolution of the Big Bang singularity.\n
