论文摘要
我们通过提供一组完整的Landau多项式来表征无数理论的奇异性集。我们找到了高斯 - 曼宁连接的一般形式。我们表明，对于无质量的理论，对动量的依赖性脱离了对耦合和维度的依赖。后者完全被吸收到一组对运动学变量不依赖的矩阵中。
We characterize the singularity set of massless theories by giving a complete set of the Landau polynomials. We find the general form of Gauss-Manin connection. We show that for massless theories the dependence on momenta decouples from the dependence on coupling and dimension. The latter is completely absorbed into a set of matrices that have no dependence on kinematic variables.
