摘要 如果平面图G的最大度Δ(G)=V|(G)|-k,k=1,2,…,则称G为一个hk-图,k=1,2的hk-图称为高度平面图.研究了高度平面图G的列表L(p,q)-标号问题,给出了高度平面图G的列表L(p,q)-标号数λl(G;p,q)的上界,并对h1-图证明了λl(G;p,q)≤(2q-1)Δ+6(p-q);对h2-图有λl(G;p,q)≤(2q-1)Δ+8p-6q-1. Let G be a planar graph, for k = 1,2,…, we call G an hk-graph, if △(G) = |V( G) | -k. In this paper, we studied the upper bound of λl(G;p,q) on planar graphs with high maximum degree, and prove that λl(G;p,q) ≤(2q- 1)△ +6(p-q) for ht-graph and λl(G;p,q) ≤(2q- 1)(G) △+8p-6q- 1 for h2-graph.
