A Real-Space Renormalization Group for Random Surfaces
arXiv:hep-lat/9510003 · doi:10.1016/0550-3213(95)00664-8
Abstract
We propose a new real-space renormalization group transformation for dynamical triangulations. It is shown to preserve geometrical exponents such as the string susceptibility and Hausdorff dimension. We furthermore show evidence for a fixed point structure both in pure gravity and gravity coupled to a critical Ising system. In the latter case we are able to extract estimates for the gravitationally dressed exponents which agree to within 2-3% of the KPZ formula.
