L(2, 1)-coloring and irreducible no-hole coloring of lexicographic product of graphs
An L(2, 1)-coloring (or labeling) of a graph G is a mapping [Formula: see text] such that [Formula: see text] if [Formula: see text] and [Formula: see text] if [Formula: see text] The span of an L(2, 1)-coloring is the maximum color assigned by it. The minimum of span of all possible L(2, 1)-colorin...
