在全阶费米子中,我们构造了D=10II型超对称双场理论。对于32个超荷,我们拼写出精确的N=2超对称变换规则。所构造的作用量将IIA型和IIB型超引力关于O(10,10)T对偶和一对局域洛伦兹群或自旋(1,9)×自旋(9,1)以明显协变的方式统一起来,除了通常的超重力性的一般协方差或广义微分同态。虽然这一理论是独一无二的,但解决方案是双重的。IIA型和IIB型超引力被认为是两种不同类型的解,而不是两种不同的理论。
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. The constructed action unifies type IIA and IIB supergravities in a manifestly covariant manner with respect to O(10,10) T-duality and a pair of local Lorentz groups, or Spin(1,9)×Spin(9,1), besides the usual general covariance of supergravities or the generalized diffeomorphism. While the theory is unique, the solutions are twofold. Type IIA and IIB supergravities are identified as two different types of solutions rather than two different theories.
