摘要
A strong edge-coloring of a graph G = (V, E) is a partition of its edge set E into induced matchings. We study bipartite graphs with one part having maximum degree at most 3 and the other part having maximum degree Delta. We show that every such graph has a strong edge-coloring using at most 3 Delta colors. Our result confirms a conjecture of Brualdi and Quinn Massey (1993) for this class of bipartite graphs.
