A note on M2-branes in opposite charge

Understand

The flux singularity that arise when branes are put in an oppositely charged background is a wildly discussed issue and in this paper the problem is investigated further.

• New AdS world volume (anti-)M2-brane solutions are constructed by placing the brane in a background where the charge dissolved in the flux is opposite that of the brane.
• A topological obstruction is derived to show how the singularity develops during localisation of this solution and any similarly constructed solution.
• Furthermore the singularity is shown not to be possible to hide behind a horizon, which would have given credence to a possible M-theory resolution.
