Abstract

Due to the difficulties of finding superconformal Lagrangian theories for multiple M2-branes, we will in this paper instead focus on the field equations. By relaxing the requirement of a Lagrangian formulation we can explore the possibility of having structure constants fABCDf^{ABC}{}_D satisfying the fundamental identity but which are not totally antisymmetric. We exemplify this discussion by making use of an explicit choice of a non-antisymmetric fABCDf^{ABC}{}_D constructed from the Lie algebra structure constants fabcf^{ab}{}_c of an arbitrary gauge group. Although this choice of fABCDf^{ABC}{}_D does not admit an obvious Lagrangian description, it does reproduce the correct SYM theory for a stack of NN D2-branes to leading order in gYM1g_{YM}^{-1} upon reduction and, moreover, it sheds new light on the centre of mass coordinates for multiple M2-branes.
