L(2, 1)-labeling of some special graphs
The L(2, 1)-labeling of a graph G is a mapping f : (V(G) → Z* such that | f(u) - f(v) | ≥ 2 if d(u, v) = 1 and | f(u) - f(v) | ≥1 if d(u,v) = 2. The L(2, 1)-labeling, number of G, denoted by λ(G), is the smallest number k such that G has an L(2, 1)-labeling with f(v) ≤ k for all v ϵ V(G). This paper...
