图G的线性2-荫度la2:(G)是将G分解为k个边不交的森林的最小整数k,其中每个森林的分支树的长度至多为2的路.给出了Halin图G的线性2-荫度.
The linear 2 -arboricity laz (G) of a graph G is the least integer k such that G can be partitioned into k edge-disjoint forests, whose component trees are paths of length at most 2. in this paper, the linear 2-arboricity of Haling graphs was derived.
