SUMMARY:The wavefunction of the de Sitter universe - Guilherme Pimentel

DESCRIPTION:I will review the wavefunctional approach to cosmological pert
 urbations\, with an emphasis in perturbations of a de Sitter background. A
 s applications that are of interest in inflationary cosmology\, this appro
 ach allows one to determine\, up to a few constants\, all three point func
 tions of gravitational waves in de Sitter space. It also gives an alternat
 ive point of view on the inflationary consistency conditions\, which relat
 e the local non-gaussianity to the power spectrum. It is also the natural 
 framework to understand the analogies between AdS/CFT and dS/CFT.
