Abstract

It has been shown that non-geometric fluxes appear in ten-dimensional supergravity by performing a field redefinition. Following a similar strategy in double field theory surprisingly allows for a geometric interpretation of these fluxes. More precisely, the Q-flux appears as part of a dual curvature scalar, reminiscent of the geometric flux f. The R-flux turns out to be a tensor and appears in the same way as the usual H-flux does. Solving the strong constraint connects this formalism to the ten-dimensional approach. Furthermore, some recent lifts of four-dimensional gauged supergravity to double field theory can be matched.
