摘要 设μ(G)表示一个图G的Mycielski图,λ(G)为G的L(2,1) 标号数.给出了λ(μ(G))的上、下界和λ(μ(G))达到下界(|G|+1)的一个充分条件. Let μ(G) denote the Mycielskian of a graph G and λ(G) denote the L(2,1)-labelling number of G.This paper provided some lower and upper bounds for λ(μ(G)) as well as a sufficient condition such that λ(μ(G))= |G| + 1.
