摘要
The strong chromatic index s'(G) is the minimum integer t such that there is an edge-coloring of G with t colors in which every color class is an induced matching. Brualdi and Quinn conjecture that for every bipartite graph G, s'(G) is bounded by Delta(1)Delta(2), where Delta(1) and Delta(2) are the maximum degrees among vertices in the two partite sets. We give the affirmative answer for Delta(1) = 2. (C) 2007 Elsevier B.V. All rights reserved.
