RG flows from Spin(7), CY 4-fold and HK manifolds to AdS, Penrose limits and pp waves

Umut Gursoy, Carlos Nunez, Martin Schvellinger

We obtain explicit realizations of holographic renormalization group (RG) flows from M-theory, from E^{2,1} \times Spin(7) at UV to AdS_4 \times \tilde{S^7} (squashed S^7) at IR, f…
