Structure and enumeration of ( 3 + 1 ) - free posets ( extended

A poset is (3 + 1)-free if it does not contain the disjoint union of chains of length 3 and 1 as an induced subposet. These posets are the subject of the (3 + 1)-free conjecture of Stanley and Stembridge. Recently, Lewis and Zhang have enumerated graded (3+1)-free posets, but until now the general enumeration problem has remained open. We enumerate all (3 + 1)-free posets by giving a decomposit...

Structure and Enumeration of (3 + 1)-free Posets

A poset is (3 + 1)-free if it does not contain the disjoint union of chains of length 3 and 1 as an induced subposet. These posets play a central role in the (3 + 1)-free conjecture of Stanley and Stembridge. Lewis and Zhang have enumerated (3+1)-free posets in the graded case by decomposing them into bipartite graphs, but until now the general enumeration problem has remained open. We give a f...

Triangle-Free Outerplanar 3-Graphs Are Pairwise Compatibility Graphs

A graph G = (V,E) is called a pairwise compatibility graph (PCG) if there exists an edge-weighted tree T and two non-negative real numbers dmin and dmax such that each vertex u ′ ∈ V corresponds to a leaf u of T and there is an edge (u′, v′) ∈ E if and only if dmin ≤ dT (u, v) ≤ dmax in T . Here, dT (u, v) denotes the distance between u and v in T , which is the sum of the weights of the edges ...
