摘要

The 1/N1/N expansion of the weak coupling phase of two-dimensional QCD on a sphere is constructed. It is demonstrated that the phase transition from the weak to the strong coupling phase is induced by instantons. A double scaling limit of the theory at the point of the phase transition is constructed, the value of string susceptibility is determined to be γstr=1\gamma_{str}=-1. The possibility of instanton induced large NN phase transitions in four dimensional QCD is explored.
