Stringy Unification of Type IIA and IIB Supergravities under N=2 D=10
Supersymmetric Double Field Theory    [PDF]

To the full order in fermions, we construct D=10 type II supersymmetric double field theory. We spell the precise N=2 supersymmetry transformation rules as for 32 supercharges. In terms of stringy differential geometry we have previously developed beyond Riemann, our action treats R-R sector democratically and unifies type IIA and IIB supergravities in a manifestly covariant fashion, with respect to O(10,10) T-duality and a pair of local Lorentz groups, Spin(1,9) \times Spin(9,1), in addition to the usual general covariance of the supergravities.
