| Abstract: | It has been shown by MacGillivray and Seyffarth (Austral. J. Combin. 24 (2001) 91) that bridgeless line graphs of complete graphs, complete bipartite graphs, and planar graphs have small cycle double covers. In this paper, we extend the result for complete bipartite graphs, and show that the line graph of any complete multipartite graph (other than K1,2) has a small cycle double cover. |
