nLab M-brane

Idea

There are two types of black brane solutions in 11-dimensional supergravity, one of dimension $2+1$, one of dimension 5+1. These are thought to correspond to a fundamental 2-brane and its EM dual, called the

• M2-brane (fractional M2-brane)

• M5-brane (half M5-brane)

• MK6-brane

• MO9-brane

• M-wave

The M2-brane carries electric charge under the supergravity C-field. The M5-brane is the dual magnetic charge.
