Graphs in Hyperbolic Geometry

Krioukov et al.[1] recently published a paper in which they consider a graph model with many interesting properties. In particular it has a power-law degree sequence, and its average degree, power-law exponent and clustering coefficient are all independently adjustable. In its simplest form it consists of N vertices uniformly distributed on a disk of radius R in a 2-dimensional hyperbolic space of curvature -1. Two vertices are joined by an edge if their hyperbolic distance is at most R. In this talk we present the basic model and its extensions.
