In this talk\, I will focus on two specific CFT3s with AdS4xS 7 gravity duals that arise as infrared fixed points of the ABJM M2-brane f ield theory deformed with a certain quadratic and a certain cubic superpot ential. In both cases\, the AdS4xS7 product is warped and the metric on S7 is squashed and stretched. In the quadratic case\, I will show how Except ional Field Theory techniques can be used to compute the entire spectrum. In the cubic case\, I will show that the spectrum exhibits a space-invader s scenario\, similar to that known to occur for another squashed AdS4xS7 s olution.\n LOCATION:https://researchseminars.org/talk/PUHET/2/ END:VEVENT END:VCALENDAR
