... probability that a random threshold graph is Hamiltonian. There is a nice connection between Hamiltonicity and a threshold graph’s creation sequence. For more background on Hamiltonian threshold graphs, ... natural, equivalent models for random threshold graphs and use these models to deduce a variety of properties of random threshold graphs. Specifically, a random threshold graph...

... subgraph of a threshold graph is again a threshold graph, so G − u is threshold. Conversely, suppose u is an extremal vertex of G and that G − u is a threshold graph. Let x be a threshold representation ... property of being a threshold graph is a hereditary property of graphs. By this we mean • if G is a threshold graph and H is isomorphic to G, then H is a threshold graph, a...
