Two-dimensional Groups, Orbifolds and Tilings
Given the triangulation of a 2-dimensional orbifold in terms of the Delaney{Dress symbol of a periodic tiling, we discuss how to compute it's orbifold symbol, as deened by J. Conway. It is shown that the number of types of equivariant tilings depends only on the \form" of the corresponding orbifold symbols. The method is applied to obtain a reened classiication of equivariant tilings for certai...
متن کاملOn Three-Dimensional Space Groups
A entirely new and independent enumeration of the crystallographic space groups is given, based on obtaining the groups as fibrations over the plane crystallographic groups, when this is possible. For the 35 “irreducible” groups for which it is not, an independent method is used that has the advantage of elucidating their subgroup relationships. Each space group is given a short “fibrifold name...
متن کاملThree Dimensional Manifolds, Kleinian Groups and Hyperbolic Geometry
1. A conjectural picture of 3-manifolds. A major thrust of mathematics in the late 19th century, in which Poincaré had a large role, was the uniformization theory for Riemann surfaces: that every conformai structure on a closed oriented surface is represented by a Riemannian metric of constant curvature. For the typical case of negative Euler characteristic (genus greater than 1) such a metric ...
متن کاملHyperbolic groups with 1-dimensional boundary
If a torsion-free hyperbolic group G has 1-dimensional boundary ∂∞G, then ∂∞G is a Menger curve or a Sierpinski carpet provided G does not split over a cyclic group. When ∂∞G is a Sierpinski carpet we show that G is a quasiconvex subgroup of a 3-dimensional hyperbolic Poincaré duality group. We also construct a “topologically rigid” hyperbolic group G: any homeomorphism of ∂∞G is induced by an ...
متن کاملHyperbolic 2-Dimensional Manifolds with 3-Dimensional Automorphism Groups I
Let M be a Kobayashi-hyperbolic 2-dimensional complex manifold and Aut(M) the group of holomorphic automorphisms of M . We showed earlier that if dimAut(M) = 3, then Aut(M)-orbits are closed submanifolds in M of (real) codimension 1 or 2. In this paper we classify all connected Kobayashi-hyperbolic 2-dimensional manifolds with 3-dimensional automorphism groups in the case when every orbit has c...
