摘要
l1-图是一个能规模嵌入到超立方体中的图,研究了树、单圈图及其线图的l1-嵌入性.证明了树、单圈图与它们的线图同时都是l1-图.
An l1-graph is a graph that can be scale-embedded embedded into the hypercube.This paper studies the l1-embeddability of trees,unicyclic graphs and their line graphs.We prove that all trees,unicyclic graphs and their line graphs are l1-graphs.
