关于图星边染色的综述

A survey on star edge-coloring of graphs

Hui Lei, Yongtang Shi

摘要:

多重图$G$的星色指数,记为$χ'_{st}(G)$,是为了使$G$的边不存在长度为4的路或圈是双色的,对$G$的边进行适当着色所需的最小颜色数。 本文对图的星色指数的结果做了一个总结, 给出了一些有趣的证明和技巧, 并收集了一些公开问题和猜想.

英文摘要:

The star chromatic index of a multigraph $G$, denoted $χ'_{st}(G)$, is the minimum number of colors needed to properly color the edges of $G$ such that no path or cycle of length four is bicolored. We survey the results of determining the star chromatic index, present the interesting proofs and techniques, and collect many open problems and conjectures.
