The charge- or spin-density-wave formation in one-dimensional electron systems under an incommensurate potential is shown to be characterized by infinitely many order parameters and infinitely many mean-field solutions with almost degenerate energies. The complexity of the solutions is described by ultrametricity. The observed field-induced spin-density-wave transition of 2D systems is discussed in this context.
