1/N expansion in two-dimensional lattice gauge theory

Abstract

We use the method of orthonormal polynomials to investigate the large N limit of the two‐dimensional lattice gauge theory. The 1/N² and 1/N⁴ corrections to the vacuum energy and the expectation value of the Wilson loop operator are calculated in the low temperature phase (λ ≡g² NN becomes large, and hence there are no 1/N corrections in this phase.
