Multiple Membranes from Gauged Supergravity

Understand

Starting from gauged N=8 supergravity in three dimensions we construct actions for multiple membranes by taking the limit to global supersymmetry for different choices of the embedding tensor.

• This provides a general framework that reproduces many recent results on multiple membrane actions as well as generalisations thereof.
• As examples we discuss conformal (non-conformal) gaugings leading to multiple M2-branes (D2-branes) and massive deformations of these systems.
