Motivated by a recent formulation of M5-branes derived from the BLG model, we generalize the earlier Lagrangian formulation based on a decomposition of spacetime into (D-1) dimensions plus a special dimension, to construct Lagrangian formulations based on a generic decomposition of spacetime into D' and D″=D-D' dimensions. Although the Lorentz symmetry is not manifest, we prove that the action is invariant under modified Lorentz transformations. © 2010 Elsevier B.V.journal article10.1016/j.nuclphysb.2010.04.0152-s2.0-77953172510WOS:000278875800001
