要旨:
The double field theory monopole solution by Berman and Rudolph is shown to
reproduce non-geometric backgrounds with non-vanishing Q- and R-flux upon an
appropriate choice of physical and dual coordinates. The obtained backgrounds
depend non-trivially on dual coordinates and have only trivial monodromies.
Upon smearing the solutions along the dual coordinates one reproduces the known
$5^2_2$ solution for the Q-brane and co-dimension 1 solution for the R-brane.
The T-duality invariant magnetic charge is explicitly calculated for all these
backgrounds and is found to be equal to the magnetic charge of (unsmeared)
NS5-brane.
