If you have a question about this talk, please contact Mustapha Amrani. Mathematics and Applications of Branes in String and M-theory 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. In this talk, it is shown that a ten-dimensional field redefinition results in a Q-flux term in the NSNS Lagrangian. This change of field basis is inspired by generalized geometry. We argue that this new field basis provides a good description of certain non-geometric configurations. In particular, using the new basis, a dimensional reduction can be performed, in which the Q-flux term gives rise to the expected term in the four-dimensional potential. We also discuss the global issues of this set-up. This talk is part of the Isaac Newton Institute Seminar Series series. ## This talk is included in these lists:- All CMS events
