Disjointness of Moebius from Horocycle Flows

Part of the Developments in Mathematics book series (DEVM, volume 28)


We formulate and prove a finite version of Vinogradov’s bilinear sum inequality. We use it together with Ratner’s joinings theorems to prove that the Moebius function is disjoint from discrete horocycle flows on \(\Gamma \setminus S{L}_{2}(\mathbb{R})\), where \(\Gamma \subset S{L}_{2}(\mathbb{R})\) is a lattice.
