WebFoliations of Hilbert modular surfaces Curtis T. McMullen∗ 21 February, 2005 Abstract The Hilbert modular surface XD is the moduli space of Abelian varieties A with real multiplication by a quadratic order of discriminant D > 1. The locus where A is a product of elliptic curves determines a finite union of algebraic curves X WebAug 14, 2015 · The S2 library starts by projecting the points/regions of the sphere into a cube, and each face of the cube has a quad-tree where the sphere point is projected into. After that, some transformation occurs (for more details on why, see the Google presentation) and the space is discretized, after that the cells are enumerated on a Hilbert …

WebMar 17, 2016 · The way of computing this curve is the following. First we define the first order Hilbert Curve as the one shown in figure (the one for n = 1), so that it fits in a 1x1 square. We than make four copies of this curve, spacing them in a 4x4 square, so that they all present the "concavity" towards the left side.
