For some solutions of M-theory\, mIIA and IIB obtained from uplift\, I will presen t the spectrum of KK gravitons and discuss a persistent form of universali ty when solutions with same (super)symmetry and supergravity spectrum are present in different theories. The masses thus found can be obtained from an SL(8)-covariant mass matrix whose trace provides the universal coeffici ents.\n\nIn the second part of the talk\, I will discuss the spectrum of K K gravitons around the N=2 AdS_4 solution that is dual to the IR of a cubi c deformation of ABJM. This solution cannot be obtained from uplift of an N=8 D=4theory\, and this seems to be linked to the fact that its metric ca nnot be isometrically embedded in R^8. Further\, the allocation of modes w ith different spins in N=2 supermultiplets cannot be made KK level by KK l evel\, but needs space invaders.\n LOCATION:https://researchseminars.org/talk/EGSS/17/ END:VEVENT END:VCALENDAR
