Two-logarithm matrix model with an external field
Abstract
We investigate the two-logarithm matrix model with the potential X+α(1+X)+β(1-X) related to an exactly solvable Kazakov-Migdal model. In the proper normalization, using Virasoro constraints, we prove the equivalence of this model and the Kontsevich-Penner matrix model and construct the 1/N-expansion solution of this model.
