Norm estimates of almost Mathieu operators

Florin P. Boca, Alexandru Zaharescu

We estimate the norm of the almost Mathieu operator $H_{θ, λ} = U + U^{*} + (λ /2) (V + V^{*})$ in the rotation $C^{*}$ -algebra $A_{θ} = C^{*} (U, V u ni t a r i es; U V = e^{2 π i θ} V U)$ . In this process, we signifi…

On the distribution of the Farey sequence with odd denominators

F. P. Boca, C. Cobeli, A. Zaharescu

We prove some asymptotic results on the distribution of h-tuples of consecutive Farey fractions of order Q with odd denominators as $Q \to \infty$ .

On the index of Farey sequences

F. P. Boca, R. N. Gologan, A. Zaharescu

We prove some asymptotic formulae concerning the distribution of the index of Farey fractions of order Q as $Q \to \infty$ .
