摘要
考虑了任意维时空中的低能光子-光子散射问题，并将相互作用扩展到包含涉及任意数目光子的散射事件。QED 中这些过程的有效相互作用拉格朗日量已以确定为显式协变的形式。这一推广揭示了弱场 Euler-Heisenberg 拉格朗日量的结构，并表明其分量不变函数的系数不仅与时空维数相关，而且与伯努利多项式的系数相关。

备注
In the revised version, the results have been expressed in terms of Bernoulli polynomials instead of generalized zeta functions; they agree for spinor QED with those of Schubert and Schmidt (obtained differently by path integral methods).
