- Abstract
- The authors reinterpret an approximation of the plane matrix model due to Wegner (1967) as a critical Gaussian spin model or a massless free Euclidean Bose field or a lattice. This enables the computation of the two-point function in terms of differences of covariances of Euclidean fields.
