摘要：
We introduce a model for random chordal graphs. We determine the thresholds for: the first edge, completeness, isolated vertices and connectivity. Like the Erdos-Renyi model, the thresholds for isolated vertices and connectivity are the same. Unlike the Erdos-Renyi model in which the threshold occurs at 1/2 n log n edges, this threshold occurs at O(n2) edges.
