    Directions in hyperbolic lattices


    Marklof, J & Vinogradov, I, 2018, ‘Directions in hyperbolic lattices’. Journal für die reine und angewandte Mathematik, vol 2018., pp. 161-186


    It is well known that the orbit of a lattice in hyperbolic n-space is uniformly distributed when projected radially onto the unit sphere. In the present work, we consider the fine-scale statistics of the projected lattice points, and express the limit distributions in terms of random hyperbolic lattices. This provides in particular a new perspective on recent results by Boca, Popa, and Zaharescu on 2-point correlations for the modular group, and by Kelmer and Kontorovich for general lattices in dimension n = 2.
