摘要:

利用组合零点定理和权转移法, 研究了最大度 $\varDelta \left( G \right) \geqslant 8$ 且最大平均度 ${\rm{mad}}\left( G \right) < \frac{{14}}{3}$ 的图 $G$ 的邻和可区别列表全染色, 确定了该类图的邻和可区别全可选择数不超过 $\varDelta \left( G \right) + 3$ .

关键词: 组合零点定理, 邻和可区别全可选择数, 权转移法

Abstract:

This paper explores the neighbor sum distinguishing list total coloring of graphs $G$ with maximum degree $\varDelta \left( G \right) \geqslant 8$ and maximum average degree ${\rm{mad}}\left( G \right) < \frac{{14}}{3}$ . By applications of the Combinatorial Nullstellensatz and discharge method, moreover, it is shown that the neighbor sum distinguishing total choice number of the graphs does not exceed $\varDelta \left( G \right) + 3$ .

Key words: Combinatorial Nullstellensatz, neighbor sum distinguishing total choice number, discharge method
