论文摘要
世界表的加倍表述提供了弦理论的描述，其中t偶尔被提升为明显的对称性。在这里，我们将此方法扩展到$ \ Mathcal {n} =（2,2）$ superspace，为Bi-Hermitian/广义Kähler目标空间提供了加倍的配方。该理论是通过单个函数来描述的，即加倍的kähler电位，并补充了明显的$ \ natercal {n} =（2,2）$约束。几个示例用来说明这一结构，包括对$ \ Mathcal {n} =（2,2）$ T折的讨论。
The doubled formulation of the worldsheet provides a description of string theory in which T-duality is promoted to a manifest symmetry. Here we extend this approach to $\mathcal{N}=(2,2)$ superspace providing a doubled formulation for bi-Hermitian/generalised Kähler target spaces. The theory is described by a single function, a doubled-generalised Kähler potential, supplemented with a manifestly $\mathcal{N}=(2,2)$ constraint. Several examples serve to illustrate this construction, including a discussion of the $\mathcal{N}=(2,2)$ description of T-folds.
