考虑使得图G存在无重复的k-重n-染色的所有数对( n,k),其比值nk 的下确界定义为图G的无重复分数染色数。圈图的无重复分数染色数在文献中已有研究,除了C10,C14和C17之外的所有圈图的无重复分数染色数都已被确定,讨论并给出了这3个圈图的无重复分数染色数的上下界。
攷慮使得圖G存在無重複的k-重n-染色的所有數對( n,k),其比值nk 的下確界定義為圖G的無重複分數染色數。圈圖的無重複分數染色數在文獻中已有研究,除瞭C10,C14和C17之外的所有圈圖的無重複分數染色數都已被確定,討論併給齣瞭這3箇圈圖的無重複分數染色數的上下界。

The fractional Thue chromatic number of a graph G was defined as the infimum of nk such that there existed a k-tuple nonrepetitive n-colouring of G.The fractional Thue chromatic numbers of all cycles were determined .The exceptional cases were C10 , C14 , and C17 .Some upper and lower bounds for the frac-tional Thue chromatic number of these cycles were presented .
