DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/50/">No
  manifest T-duality at alpha'^3</a>\nby Linus Wulff (Masaryk University) a
 s part of AnLy Strings and Fields online seminars\n\n\nAbstract\nT-duality
  leads to a (continuous) O(d\,d) symmetry of the tree-level closed string 
 effective action reduced from D=10 to 10-d. However\, this symmetry appear
 s only after certain field redefinitions. I will argue that when the $\\al
 pha^{\\prime \\\,3}$ correction is included these field redefinitions cann
 ot be lifted to ten dimensions. This poses a problem for approaches like g
 eneralized geometry and double field theory\, which assume an O(d\,d) stru
 cture is present before reduction.\n
