在具有恒定背景曲率的二维时空中考虑了大量标量场和自旋1/2场，并且存在外部恒定场。对于每种情况，欧拉-海森堡有效作用量和对产生率以及它们对曲率和外场的依赖性都被精确地确定。
Massive scalar and spin 1/2 fields are considered on a two‐dimensional space‐time with constant background curvature and in the presence of an external constant field. For each case, the Euler–Heisenberg effective action and the pair creation rate and their dependence on both the curvature and external field is determined exactly.
