Conformal Gravity and AdS/CFT
Speaker(s): Kostas Skenderis
Abstract: TBA

Holographic Non-Gaussianity
Speaker(s): Kostas Skenderis
Abstract: We discuss holographic models for the inflationary epoch. We show how cosmological observables such as the primordial spectrum and non-Gaussianities can be computed via computations of correlation functions of a dual three dimensional QFT (without gravity!) We present a general class of models that ... read more

Holography for cosmology
Speaker(s): Kostas Skenderis
Abstract: We propose a holographic description of four dimensional single scalar inflationary universes, in particular asymptotically de Sitter cosmologies and power-law inflation. We show how cosmological observables such as the primordial power spectrum and non-gaussianities are encoded in correlation funct... read more

Non-conformal holography
Speaker(s): Kostas Skenderis
Abstract: We discuss holography for geometries that are asymptotic to non-conformal brane backgrounds. The near-horizon limit of all non-conformal branes, including D-branes and the fundamental string but excluding five-branes, is conformal to $AdS_{p+2} imes S^{8-p}$ with a linear dilaton. They exhibit a ge... read more
