Bagger–Lambert–Gustavsson action
Introduction In theoretical physics, in the context of M-theory, the action for the ''N''=8 M2 branes in full is (with some indices hidden)::where ,  is a generalisation of a Lie bracket which gives the group constants.The only known compatible solution however is::using the Levi-Civita symbol which is invariant under SO(4) rotations. M5 branes can be introduced by using an infinite symmetry group.The action is named after Jonathan Bagger, Neil Lambert, and Andreas Gustavsson.
