本文讨论了微扰论中平面费曼图类的几个性质。我们证明了在任何场论中平面环图的数目都是指数增长的,并计算了φ 3和φ4的详细渐近行为。我们讨论了这一结果的收敛性的系列及其关系到各种半经典不稳定性,特别是非阿贝尔规范理论的影响。我们还导出了平面图的一个泛函积分方程。
We discuss several features of the class of planar Feynman diagrams in perturbation theory. We show that the number of planarn-loop diagrams grows exponentially innin any field theory, and calculate the detailed asymptotic behavior for φ3and φ4. We discuss the implications of this result for the convergence of the series and its relation to various semiclassical instabilities, with special reference to non-Abelian gauge theories. We also derive a functional integral equation for planar graphs.
