Using the standard saddle-point method, we find an explicit relation for the
large-N limit of the free energy of an arbitrary generalized
2D Yang-Mills
theory in the weak (AAc) region, we
investigate carefully the specific fourth Casimir theory, and show that the
ordinary integral equation of the density function is not adequate to find the
solution. There exist, however, another equation which restricts the
parameters. So one can find the free energy in the strong
region and show that the theory has a third-order phase transition.
