Two-dimensional QCD is a string theory
Abstract
The partition function of two-dimensional QCD on a Riemann surface of area A is expanded as a power series in {1}/{N and A }. It is shown that the coefficients of this expansion are precisely determined by a sum over maps from a two-dimensional surface onto the two-dimensional target space. Thus two-dimensional QCD has a simple interpretation as a closed string theory.
