摘要
The linear arboricity la(G) of a graph G is the minimum number of linear forests which partition the edges of G. In this paper, it is proved that for a planar graph G, if Delta(G) a parts per thousand yen 7 and G has no 5-cycles with chords, or Delta(G) a parts per thousand yen 5 and G has no 5-, 6-cycles with chords.
