SUMMARY:Supersymmetric Double Field Theory: Stringy Reformulation of Super
 gravity - Park\, J-H (Sogang University)

DESCRIPTION:This talk aims to illustrate  our recent supersymmetric extens
 ion of double field theory and its connection to supergravity.\nIn terms o
 f  novel  stringy differential geometry we propose\, our action consists o
 f five simple terms - two bosonic plus three fermionic -  and manifests no
 t only diffeomorphism and one-form gauge symmetry of B-field\, but also O(
 10\,10) T-duality as well as a direct product of two local Lorentz symmetr
 ies\, SO(1\,9) times SO(9\,1). A gauge fixing that identifies the double l
 ocal Lorentz groups reduces our action to the N=1 supergravity in ten dime
 nsions.\n\n
