DESCRIPTION:Non-geometric fluxes appear in four-dimensional gauged supergr
 avities through specific terms in the potential. These terms are of phenom
 enological interest for the matters of moduli stabilization or de Sitter s
 olutions. Unfortunately\, their ten-dimensional origin\, and their relatio
 n to non-geometry\, remain unclear. In this talk\, I will present recent p
 rogress on these questions. Thanks to a field redefinition in ten-dimensio
 nal supergravity\, one makes the non-geometric Q and R fluxes appear\, and
  additionally restores a standard notion of geometry. A dimensional reduct
 ion can then be performed\, and the four-dimensional non-geometric terms o
 f the scalar potential are recovered.\n\n
