Web1. Lecture on Coxeter Groups In the first lecture, we construct a few lattices in SO(p,1) by the geometric method, when p≤ 9. 1.1. Introduction. — The geometric method of construction of lattices has been ini-tiated by Poincar´e in 1880. In his construction, the group Gis the group PO+(2,1) of isometries of the hyperbolic plane H2. Web14 dec. 2024 · 1 Answer Sorted by: 8 Just to make the method as concrete as possible, I'll compute the growth rate for the fundamental group G of a surface of genus two. The Cayley graph of G is the 1-skeleton of a tiling of the hyperbolic plane by regular octagons, with eight octagons meeting at each vertex.
