Generalized conformal symmetry and recovery of image in multiple M2 and D2 branes Original Research Article

We investigate conformal symmetries of the Aharony–Bergman–Jafferis–Maldacena (ABJM) theory for multiple M2 branes and the Lorentzian Bagger–Lambert–Gustavsson (L-BLG) theory which can be obtained by taking a scaling limit image of the ABJM theory. The conformal symmetry is maintained in the L-BLG by considering general space–time varying solutions to the constraint equations. The dual geometry is reduced to image image in the scaling limit and has the same conformal symmetry. The curvature radius R satisfies image (image and image are the d-dimensional Planck lengths and the string scale), and the theory is in a region where an image expansion is not valid. We also study how the image covariance is recovered in the image geometry by taking the scaling limit.
