The method shows that the problem has clear signs of a crossover, but is only able to access (unscaled) finite temperatures above the transition point. The solution of the problem using this method displays a curious duality.4 pages, 2 figuresDisordered Systems and Neural NetworksStatistical Mechanicstext
