BLOCK RENORMALIZATION WITHIN DYNAMICAL TRIANGULATION FORMALISM OF 2-DIMENSIONAL QUANTUM-GRAVITY

We define a specific block renormalization within dynamical triangulat ion formalism of two-dimensional quantum gravity. We apply it to surfa ces with 400,000 triangles generated by Monte Carlo simulation and mea sure loop length distribution and coordination number distribution. Th e former preserves the universal scaling behavior in Ref. 1) without a ny redefinition of the scaling parameter, while the latter converges t o a certain distribution. These results strongly suggest the existence of a fixed-point action.
