Two-dimensional quantum gravity and current algebra on a torus = 토러스 위에서 이차원 양자중력 이론과 흐름대수

Two dimensional induced quantum gravity on a torus is analyzed. By introducing the non-analytic Green``S function, we evaluate the correlation functions of the metric from the Ward identity and show that the two dimensional quantum gravity on torus is still ralated to SL(2, R) cruuent algebra. We cast the supersymmetric extension to Polyakov``s work and find that the central charge of current algebra related to the (2, 0) supergravity is real for any space time dimension d. This fact is originated from the vanishing of "dimensionality" (number of boson minus number of fermion generators) of OSP(2/2) algebra.
