摘要：
The metric of two-dimensional quantum gravity interacting with conformal matter is believed to collapse to a branched polymer metric when the central charge c > 1, We show analytically that the spectral dimension, d(S), of such a branched polymer phase is 4/3. This is in good agreement with numerical simulations for large c. (C) 1998 Elsevier Science B.V.
