Intersecting noncommutative M5-branes from covariant open supermembrane Original Research Article

We study intersecting noncommutative (NC) M5-branes from κ-invariance of an open supermembrane action with constant three-form fluxes. The κ-invariance gives rise to possible D-brane configurations for which projection operators can be determined. We construct projection operators for two types of 1/4 BPS intersecting NC M5-branes. The one is an intersection of two NC M5-branes: NC image M5 (3). The other is that of an NC M5-brane and a commutative (C) M5-brane: NC image M5 (1). An NC M5-brane can be viewed as a bound state of M5 and M2, and the configurations image (1) and image (0) are realized on the intersecting M5-branes. Taking a commutative limit the allowed intersecting M5-branes are surely reproduced: image (3) and image (1).
