| Abstract: | We develop a method to obtain the large-N renormalization group flows for matrix models of two-dimensional gravity plus branched polymers. This method gives precise results for the critical points and exponents for one-matrix models. We show that it can be generalized to two-matrix models and we recover the Ising critical points. |
