DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EGSS/8/">Non
 -abelian T-duality as a transformation in double field theory</a>\nby Aybi
 ke Catal-Ozer (Tech. U. Istanbul) as part of Exceptional geometry seminar 
 series\n\n\nAbstract\nWe show that Non-Abelian T-duality (NATD) can be des
 cribed as a coordinate dependent O(D\,D) transformation for supergravity f
 ields in the NS-NS sector and as a Pin(D\,D) transformation for the fields
  in the RR sector. This enables us to show that NATD is a solution generat
 ing transformation in Double Field Theory (DFT)\, by regarding the transfo
 rmed fields as duality twisted fields in the context ofGauged Double Field
  Theory (GDFT) of Type II strings. When the isometry algebra is non-unimod
 ular\, consistency of GDFT forces the generalized dilaton field to have a 
 linear dependence on the winding type coordinates of DFT\, implying that t
 he transformed fields satisfy the field equations of DFT in the generalize
 d supergravity frame. We also discuss briefly the analogous story for Yang
 -Baxterdeformations.\n
