Flat Coordinates , Topological Landau-Ginzburg Models and the Seiberg-Witten Period Integrals

We study the Picard-Fuchs differential equations for the Seiberg-Witten period inte-grals in N = 2 supersymmetric Yang-Mills theory. For AD -E gauge groups we derive the Picard-Fuchs equations by using the flat coordinates in the AD -E singularity theory. We then find that these are equivalent to the Gauss-Manin system for two-dimensional AD -E topological… (More)
