We consider relations of upper bound graphs, double bound graphs and posets. We first consider a characterization of chordal double bound graphs in terms of subposets Qn. Furthermore we deal with properties of posets whose upper bound graph is its double bound graph, and whose double bound graph its comparability graph, and etc.
In addition we consider hereditary double bound graphs. We know that every graph is an induced subgraph of a double bound graph. A graph G is a hereditary double bound graph if and only if every induced subgraph of G is a double bound graph. We show some properties of hereditary double bound graphs in terms of posets.
