| Abstract: | We find a general expression for the free energy of generalized two-dimensional (2D) Yang-Mills theory in the strong () region for large N. We also show that in this region, the density function of Young tableau of these models is a three-cut problem. In the specific
model, we show that the theory has a third order phase transition, like the (YM) and models. We note problems for cases where , and at the end, examine the phase structure of the model for the region.
