An illustration to interpret the equilibrium state for \(A=\mathrm{SS}\). (A) In the left panel, the yellow solid line shows the C-map, which maps any value p to a constant value, \(1-e_2\). This mapped value is labeled as \(\mu _1\). The right panel (same as a panel in Fig. 2-B) shows the equilibrium state \(\phi ^*(p)\) for \(A=\mathrm{SS}\), where the peak positions of all the classes \(\mu _{1}, \mu _{2}, \mu _{3}, \cdots\) are mapped to \(\mu _1\) by the C-map. (B) In the left panel, the yellow broken line shows the D-map, which sequentially maps the 1st peak to 2nd, 3rd, 4th peaks, and so on. The right panel illustrates how the peak position \(\mu _j\) of class-j is mapped to the peak position \(\mu _{j+1}\) of class-\((j+1)\) by the D-map.
