论文摘要
我们探讨了非河流几何形状中异构体的概念。这种几何形状包括并概括了非忠实弦理论的背景，并且可以使用双场理论的形式主义自然描述它们。采用这种方法，我们首先为恒定的扁平非河流背景求解相应的杀戮方程，并表明它们接纳了一个无限二维代数，该代数包括特定类型的超级翻译。这些对称性对应于Gomis-oguri非权利主义弦的已知世界表noe，我们现在将其解释为其非利马尼亚语双打背景的等法。我们进一步考虑了超对称双场理论的扩展，并表明相应的杀戮旋转器可以任意取决于非河流方向，从而导致“超级对称性”将其正方形为超级翻译。
We explore the notion of isometries in non-Riemannian geometries. Such geometries include and generalise the backgrounds of non-relativistic string theory, and they can be naturally described using the formalism of double field theory. Adopting this approach, we first solve the corresponding Killing equations for constant flat non-Riemannian backgrounds and show that they admit an infinite-dimensional algebra of isometries which includes a particular type of supertranslations. These symmetries correspond to known worldsheet Noether symmetries of the Gomis-Ooguri non-relativistic string, which we now interpret as isometries of its non-Riemannian doubled background. We further consider the extension to supersymmetric double field theory and show that the corresponding Killing spinors can depend arbitrarily on the non-Riemannian directions, leading to "supersupersymmetries" that square to supertranslations.
