In 2012, Lévêque, Maffray and Trotignon conjectured that if a graph does not contain an induced subdivision of \(K_4\), then it is 4-colorable. Recently, Le showed that every such graph is 24-colorable. In this paper, we improve the upper bound to 8.

没有归纳的$$ K_4 $$ K4的图的色数

在2012年,Lévêque,Maffray和Trotignon推测,如果图形不包含\(K_4 \)的诱导细分,则它是4色的。Le最近表示,每个这样的图形都是24色的。在本文中,我们将上限提高到8。
