Title
The Maximum Chromatic Index of Multigraphs with Given Δ and μ.
Abstract
Let f(Δ, μ) = max {χ′(G) | Δ (G) = Δ, μ(G) = μ} where χ′(G), Δ(G) and μ(G) denote the the chromatic index, the maximum degree and the maximum multiplicity of the multigraph G, respectively. If Δ < 2μ, then Shannon’s bound implies that the gap between f(Δ, μ) and Vizing’s bound Δ + μ can be arbitrarily large. In this note, we prove that this is also the case for Δ ≥ 2μ (see Theorem 4).
