Abstract

An Ising model on a lattice made of planar Feynman graphs, which was originally introduced by Kazakov, is studied. Its exact correspondence with a matrix model is reconsidered and a new correspondence suggested. The new nonperturbative phase of the model, recently found by one of us, is further analyzed. © 1988.
