论文摘要
我们考虑了曲率中的作用二次的2D重力模型,并将路径积分表示为SL(2,r)不变高斯功能度量的积分。我们将这些路径积分减少到Wiener路径积分的产物,并在第一个扰动顺序计算度量的相关函数。
We consider a model of 2D gravity with the action quadratic in curvature and represent path integrals as integrals over the SL(2, R) invariant Gaussian functional measure. We reduce these path integrals to the products of Wiener path integrals and calculate the correlation function of the metric in the first perturbative order.
