An equation involving the neighborhood (two-step) and line graphs
Abbreviated Journal Title
2-STEP GRAPHS; Mathematics
The neighborhood or two-step graph, N(G), of a graph G is the intersection graph of the open neighborhoods of the vertices of G, and L(G) is the line graph of G. The class of graphs for which N[L(G)] congruent to L[N(G)] consists of those graphs for which every component is either K-1, K-1,K-3, or C-n where n greater than or equal to 3 and n not equal 4.
