Boundary Effects in the BLG Theory

英文摘要：

In this paper we will analyse a system of multiple M2-branes in between two M5-branes. This will be analysed by studying Bagger-Lambert-Gustavsson (BLG) theory on a manifold with two boundaries. The original BLG theory will be modified to make it gauge and supersymmetric invariant in presence of the boundaries. However, this modified theory will only preserve half the supersymmetry of the original theory. We will also analyse the deformation of this theory caused by noncommutativity between Grassman coordinates and spacetime coordinates. Finally, we will analyse the Higgsing of this theory to deformed D2-branes with boundaries.
