Recognizing the P 4-structure of claw-free graphs and a larger graph class
The P 4-structure of a graph G is a hypergraph H on the same vertex set such that four vertices form a hyperedge in H whenever they induce a P 4 in G. We present a constructive algorithm which tests in polynomial time whether a given 4-uniform hypergraph is the P 4-structure of a claw...
