Inflationary Cosmology after Planck 2013
Abstract
I give a general review of inflationary cosmology and of its present status, in view of the 2013 data release by the Planck satellite. A specific emphasis is given to the new broad class of theories, the cosmological attractors, which have nearly model-independent predictions converging at the sweet spot of the Planck data in the (n_s,r) plane. I also discuss the problem of initial conditions for the theories favored by the Planck data.

84 pages, 23 figures, based on lectures at the Les Houches School "Post-Planck Cosmology,'' 2013. A section on inflation in supergravity is extended, a subsection on unitarity problem for Higgs inflation and related models is added, a reply to the recent critical comments on inflation by Ijjas, Steinhardt and Loeb is extended
