Asymptotic freedom, asymptotic flatness and cosmology

Understand

Holographic RG flows in some cases are known to be related to cosmological solutions.

• In this paper another example of such correspondence is provided.
• Holographic RG flows giving rise to asymptotically-free $\beta$-functions have been analyzed in connection with holographic models of QCD.
• They are shown upon Wick rotation to provide a large class of inflationary models with logarithmically-soft inflaton potentials.
