The construction of off‐shell amplitudes in closed string theory using Riemann surfaces having constant curvature −1 is explored in detail. Off‐shell string amplitudes constructed using surfaces with constant curvature −1 fail to satisfy the off‐shell factorization properties, and as a result, scattering amplitudes computed using them are ill‐defined. In this paper, we describe a procedure for systematically modifying this construction and obtain consistent off‐shell amplitudes in closed string theory satisfying the off‐shell factorization properties.

弦论和双曲几何中的壳外振幅

详细探讨了使用弦曲率为-1的黎曼曲面在闭合弦理论中构造壳外振幅的方法。使用具有恒定曲率-1的曲面构造的壳外弦振幅不能满足壳外分解特性，结果，使用它们计算的散射振幅是不确定的。在本文中，我们描述了一种程序，用于系统地修改此构造并在满足弦外分解特性的闭合弦理论中获得一致的弦外振幅。
