Abstract: |
Let a graph contains m cycles C4 of lengths 4 have a common vertex, then we denote this graph as Dm, 4.Then we study the vertex coloring, edge coloring and total coloring of Graph Dm, 4, and give the [r, s, t]-chromatic numbers of the Graph Dm, 4 when the parameters r, s, and t meet certain conditions. |
Key words: graph graph Dm,4 [r,s,t]-colouring [r,s,t]-chromatic number |
