Description

An ultraviolet-complete description of inflation may not be simple. Indeed, our best paradigm for physics at high energies seems to point towards a low-energy effective potentials with a large number of degrees of freedom. Cosmological data however shows a very simple primordial distribution of matter. I will discuss how complex inflation can give rise to universal simple predictions by analysing two distinct scenarios — one with random manyfield potential and one with poles in the kinetic terms.
