The abstract, sentence by sentence
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.

The paper
Original abstract
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.

Then, in Section [ref], we extend the results of [ref] to localised branes, showing that extremal anti M2-branes with trivial horizon topology cannot have a regular horizon.

These worries cumulated in a series of papers [ref] following on [ref] (and [ref] ), which claimed that the supergravity solutions corresponding to anti-branes have diverging NSNS 3-form fluxes [equation] near the anti-branes.

One of these tools is what has been called a topological no-go [ref] which constrain the possible configurations of the potential of the field strength $F_8-p$ associated with a D$p$-brane and force a singularity in the flux density $H_3 F_6-p$.

One such method is resolving the solutions via the Myers effect [ref] à la Polchinski-Strassler [ref] , by letting a D$(p+2)$-brane surround and cut off the singularity, created by a D$p$-brane, to a finite value.

In the case of AdS$_p+1$ solutions for the D$p$ branes of [ref] this is not the case, since there the dilaton equation of motion restricts $λ$ to a fixed value.[In [ref] $κ= 1/λ$.] It should also be noted that when a circle can be identified in the $^(H)$ section of the internal space this construction corresponds to a direct uplift from type IIA sugra to $11$D sugra.

So far neither partial smearing nor perturbative backreaction seems to be the issue that creates these singularities since the singularities develop even in fully localised solutions and in fully backreacted solutions [ref] , more general result in [ref] .
