Abstract: |
In this paper, we study the problem of the conflict-free vertex-connection number of vertex coloring graphs, and obtain an upper bound and a lower bound for the conflict-free vertex-connection number of Tn.k and an upper bound for the conflict-free vertex-connection number of TnΛ, TΛand Λd by using the structural characteristics of trees. |
Key words: conflict-free vertex-connection number tree upper bound lower bound |
