Abstract
We introduce a model for random chordal graphs. We determine the thresholds for: the first edge, completeness, isolated vertices and connectivity. Like the Erdös-Rényi model, the thresholds for isolated vertices and connectivity are the same. Unlike the Erdös-Rényi model in which the threshold occurs at 1/2n logn edges, this threshold occurs atO(n 2) edges.
