摘要
In ten- and four-dimensional supergravities, the descriptions of non-geometric configurations are different. In the former, non-geometry arises as naively non-single valued supergravity fields. In the latter, new terms, coming from non-geometric Q- and R-fluxes, appear in the four-dimensional potential. We review how these different descriptions can be linked using a ten-dimensional field redefinition, as proposed by [1]. This change of field basis results in a Q-flux term in the ten-dimensional Lagrangian, which can, for certain non-geometric set-ups, be dimensionally reduced to its four-dimensional counterpart. We briefly discuss the global issues of this construction.
