On the maximum average degree and the incidence chromatic number of a graph
We prove that the incidence chromatic number of every 3-degenerated graph G is at most Δ(G)+4. It is known that the incidence chromatic number of every graph G with maximum average degree mad(G)<3 is at most Δ (G)+3. We show that when Δ (G) ≥ 5, this bound may be decreased to Δ (G)+...
