Description
T-duality is known to generate exotic objects, which cannot be consistently described in terms of conventional supergravity. In the focus of this talk are backgrounds of DFT carrying Q or R fluxes, which are non-commutative and non-associative in the conventional description. We show that the Berman-Rudolph's DFT-monopole solution which unifies the backgrounds of NS5-brane and KK-monopole also describes these exotic backgrounds upon a choice of section condition. The resulting Q- and R-monopoles no longer have non-trivial monodromies and the only sign of non-geometry is a non-trivial dependence of the fields on dual (winding) coordinates.
