We show that, when an approximation used in this prior work is removed, the resulting improved calculation yields an alternative derivation, in the particular case studied, of the accidental curvature constraint of Hellmann and Kaminski. The result is at the same time extended to apply to almost all non-degenerate Regge-like boundary data and a broad class of face amplitudes. This resolves a tension in the literature.

我们表明，当移除先前工作中使用的近似值时，由此产生的改进计算会产生另一种推导，在所研究的特定情况下，Hellmann 和 Kaminski 的偶然曲率约束。结果同时扩展到适用于几乎所有非退化的 Regge-like 边界数据和广泛的面部振幅。这解决了文学中的紧张局势。
