论文摘要
固定ADS背景中QFT的边界相关函数应减少到平面限制中的S-Matrix元素。我们将对四点功能进行详细考虑此过程。通过最小的假设，我们严格地表明，所得的S-Matrix元素遵守分散性关系，非线性单位性条件和Froissart-Martin结合。因此，AD中的QFT为通常依赖LSZ公理的基本QFT结果提供了替代途径。
The boundary correlation functions for a QFT in a fixed AdS background should reduce to S-matrix elements in the flat-space limit. We consider this procedure in detail for four-point functions. With minimal assumptions we rigorously show that the resulting S-matrix element obeys a dispersion relation, the non-linear unitarity conditions, and the Froissart-Martin bound. QFT in AdS thus provides an alternative route to fundamental QFT results that normally rely on the LSZ axioms.
