Abstract:

The Farey sequence $\mathcal{F}_Q$ of order $Q$ is the ascending sequence of fractions $a/b$ in the unit interval $(0,1]$ such that $\gcd(a,b)=1$ and $0<a\leq b\leq Q$. The study of the Farey sequence is of independent interest because of its role in the Diophantine approximation, the circle method, and its connection to the Riemann Hypothesis, as established by the classical work of Franel and Landau. In this talk, we discuss the spacing statistics of the Farey sequence by studying equidistribution and correlation measure. In particular, we establish an estimate for the corresponding Weyl sum and explore whether correlation measure is Poissonian or non-Poissonian.

Thank you.

With kind regards,
