A claw-free graph is a graph in which no induced subgraph is a claw; i.e., any subset of four vertices has other than only three edges connecting them in this pattern. Equivalently, a claw-free graph is a graph in which the neighborhood of any vertex is the complement of a triangle-free graph .

19/05/2000 · Claw-free graphs were originally investigated as natural generalizations to line graphs [58] and have since developed into the subject of a rich area of study in graph theory [59]. Line graphs are...

The line graph L(G) of any graph G is claw-free; L(G) has a vertex for every edge of G, and vertices are adjacent in L(G) whenever the corresponding edges share an endpoint in G. A line graph L ( G ) cannot contain a claw, because if three edges e 1 , e 2 , and e 3 in G all share endpoints with another edge e 4 then by the pigeonhole principle at least two of e 1 , e 2 , and e 3 must share one ...
