Ultrametric organization of TAP states
Ultrametric organization of TAP states
Let be the open set from the quenched complexity formula. For , let be the optimizer in that formula and let minimize
Ultrametric organization conjecture. The TAP critical points at free-energy level are organized in an ultrametric tree; uniformly sampled overlaps between two such states take values in the support of . If , the ancestor states have TAP free energy , and the quenched complexity of the ancestor states is , so their number grows at most subexponentially in .
