摘要
考虑均衡完全三部图K3(n)的线性3-荫度.利用路分解的方法给出了K3(n)的线性3-荫度la3(Κ3(n))当n≡1,2,3(mod 4)时的比较紧的上界,利用线性k-荫度的基本理论分别得到了它们的下界,进而得到了特殊情况下均衡完全三部图K3(n)的线性3-荫度的确切值.
The linear 3-arboricity of balanced complete tripartite graph K3(n) is studied.It is obtained that the sharp upper bounds of linear 3-arboricity la3(K3(n)) when n≡1,2,3(mod 4) by using the method of path-factorization,as well as the lower bounds by using the elementary theory of linear k-arboricity.And then the exact values of linear 3-arboricity of balanced complete tripartite graph K3(n) in some special cases are determined.
