A Remark on the Renormalization Group Equation for the Penner Model
arXiv:hep-th/9406139 · doi:10.1103/PhysRevD.51.2014
Abstract
It is possible to extract values for critical couplings and gamma_string in matrix models by deriving a renormalization group equation for the variation of the of the free energy as the size N of the matrices in the theory is varied. In this paper we derive a ``renormalization group equation'' for the Penner model by direct differentiation of the partition function and show that it reproduces the correct values of the critical coupling and gamma_string and is consistent with the logarithmic corrections present for g=0,1.
