Constancy conjecture for the integrated density of states at inverse-beta energies

About 6 years old · traced to

Let pp be the Bernoulli parameter, let β−1(n)\beta^{-1}(n) denote the decreasing sequence appearing in the model, and let Ip,ζ(x)I_{p,\zeta}(x) be the integrated density of states at disorder parameter ζ\zeta. For n∈N∖{1}n\in\mathbb{N}\setminus\{1\}, consider the energy x=β−1(n)x=\beta^{-1}(n). Constancy conjecture. For every n∈N∖{1}n\in\mathbb{N}\setminus\{1\} and every ζ≥β−1(n)\zeta\geq\beta^{-1}(n),

Ip,ζ(β−1(n))=p1−p(1−p)n1−(1−p)n.I_{p,\zeta}(\beta^{-1}(n))=\frac{p}{1-p}\frac{(1-p)^n}{1-(1-p)^n}.

This conjecture asserts that the integrated density of states is constant in ζ\zeta on the indicated range, extending the analogous constancy established in the preceding corollary for the energies 4−β−1(n)4-\beta^{-1}(n). The supplied text gives no resolution status.
