Title
The n-ordered graphs: A new graph class
Abstract
For a positive integer n, we introduce the new graph class of n-ordered graphs, which generalize partial n-trees. Several characterizations are given for the finite n-ordered graphs, including one via a combinatorial game. We introduce new countably infinite graphs R(n), which we name the infinite random n-ordered graphs. The graphs R(n) play a crucial role in the theory of n-ordered graphs, and are inspired by recent research on the web graph and the infinite random graph. We characterize R(n) as a limit of a random process, and via an adjacency property and a certain folding operation. We prove that the induced subgraphs of R(n) are exactly the countable n-ordered graphs. We show that all countable groups embed in the automorphism group of R(n). © 2008 Wiley Periodicals, Inc.
