论文摘要
我们研究了SL（2，Z）双重性如何在非依赖性的IIB型超弦理论中实现，这是相对论弦理论的独立角。在这个角落里，我们明显地意识到SL（2，z）-invariant（p，q） - 屈服动作。这些动作的构建在与两种形式的场相反的电荷的字符串之间施加了分支。分支点由这些电荷和轴心背景字段确定。必须合并两个分支，以实现完整的SL（2，z）组。除了这些弦乐动作外，我们还构建了D-instanton和D3-Brane动作，这些动作明显地意识到了分支的SL（2，Z）对称性。
We investigate how SL(2,Z) duality is realized in nonrelativistic type IIB superstring theory, which is a self-contained corner of relativistic string theory. Within this corner, we realize manifestly SL(2,Z)-invariant (p,q)-string actions. The construction of these actions imposes a branching between strings of opposite charges associated with the two-form fields. The branch point is determined by these charges and the axion background field. Both branches must be incorporated in order to realize the full SL(2,Z) group. Besides these string actions, we also construct D-instanton and D3-brane actions that manifestly realize the branched SL(2,Z) symmetry.
