标题： The Effective Prepotential of N=2 Supersymmetric SU(N_c) Gauge Theories

摘要： 我们从由谱曲线构造的精确解中确定了具有任意数量的味数 N_f < 2N_c 的 N=2 超对称 SU(N_c) 规范理论的有效预势。 预势对于文献中提出的几种谱曲线模型是相同的。 它在所有阶次上都具有单环微扰修正的对数奇异性，从而确认了超对称的非重整化定理。 特别是，重整化的序参数及其对偶在弱耦合下都具有正确的单值变换。 我们显式地计算了一瞬子和二瞬子过程的贡献。 显示英文摘要

摘要： We determine the effective prepotential for N=2 supersymmetric SU(N_c) gauge theories with an arbitrary number of flavors N_f < 2N_c, from the exact solution constructed out of spectral curves. The prepotential is the same for the several models of spectral curves proposed in the literature. It has to all orders the logarithmic singularities of the one-loop perturbative corrections, thus confirming the non-renormalization theorems from supersymmetry. In particular, the renormalized order parameters and their duals have all the correct monodromy transformations prescribed at weak coupling. We evaluate explicitly the contributions of one- and two-instanton processes.
