Conjecture on extending the rational rotation-number height bound

Let λ=a/b\lambda=a/b and δ=r/s\delta=r/s be rational numbers with 0<λ,δ<10<\lambda,\delta<1, and let γ>1\gamma>1. Theorem 2 concerns the rational rotation number ρλ,δ=p/q\rho_{\lambda,\delta}=p/q under the assumption b>aγb>a^\gamma. The conjecture. Theorem 2 should remain valid when b>aγb>a^\gamma, allowing a possibly larger upper bound for qq that depends only on γ\gamma, aa, bb, and ss. This would extend the partial height estimate for rational rotation numbers beyond the range established with the golden-ratio exponent.
