论文摘要
我们调查了两种类型的转换，使NS-NS广义超级方程满足：$χ$ - 符号对称会改变Dilaton和量规变换，从而改变Dilaton和Vector Field $ J $。由于这些对称性，有大量的dilatons和向量场$ j $（对于固定度量和B场）满足了广义的超级强度方程，但只能将其中一些用作泊松转换的输入。给出了定义可允许的延伸的条件并提供了例子。
We investigate two types of transformations that keep NS-NS Generalized Supergravity Equations satisfied : $χ$-symmetry that shifts dilaton and gauge transformations that change both dilaton and vector field $J$. Due to these symmetries there is a large set of dilatons and vector fields $J$ that (for a fixed metric and B-field) satisfy Generalized Supergravity Equations but only some of them can be be used as input for Poisson--Lie transformations. Conditions that define the admissible dilatons are given and examples are presented.
