Holographic Renormalization of Two-Point Functions in Non-AdSNon-CFT

Abstract EN

We review recent progress on holographic renormalization in the context of the gauge-gravity correspondence when the bulk geometry is not asymptotically AdS.

The prime example is the Klebanov-Strassler background, whose dual gauge theory has logarithmically running couplings at all energy scales.

The presented formalism provides the counterterms necessary for obtaining finite two-point functions of the scalar operators in the corresponding dual gauge theories.

The presentation is self-contained and reviews all the relevant background material concerning a gauge-invariant description of the fluctuations around holographic renormalization group backgrounds.
