摘要：

We consider a model of discretized 2D gravity interacting with Ising spins where the phase boundaries are restricted to have minimal length and show analytically that the critical exponent, gamma, is 1/3 at the spin transition point. The model captures the numerically observed behavior of standard multiple Ising spins coupled to 2D gravity.
