Non-geometric Q-flux in ten dimensions
arXiv:1203.5127
Abstract
We review the main ideas of arXiv:1106.4015: A change of field variables in the NSNS Lagrangian of ten-dimensional supergravity reveals the non-geometric Q-flux expressed in terms of an antisymmetric bivector field. After a simple dimensional reduction, the corresponding term gives the known contribution in the four-dimensional potential. Problematic non-trivial monodromies of non-geometric backgrounds in ten dimensions can be absorbed in a total derivative term such that a well-defined Lagrangian is obtained.
