最小度为$3n/4$的$2$着色图的单色圈划分

Monochromatic cycle partitions of $2$-coloured graphs with minimum degree $3n/4$

Shoham Letzter

摘要:

Balogh、Barát、Gerbner、Gyárfás和Sárközy提出了以下猜想。设$G$是$n$顶点上的图,其最小度至少为$3n/4$ .然后,对于$G$的每个$2$ -边着色,顶点集$V(G)$可以被划分成两个顶点不相交的循环,每个颜色一个。我们证明,这个猜想持有$n$足够大,改善上述作者和DeBiasio和Nelsen的近似结果。

英文摘要:

Balogh, Barát, Gerbner, Gyárfás, and Sárközy proposed the following conjecture. Let $G$ be a graph on $n$ vertices with minimum degree at least $3n/4$. Then for every $2$-edge-colouring of $G$, the vertex set $V(G)$ may be partitioned into two vertex-disjoint cycles, one of each colour. We prove that this conjecture holds for $n$ large enough, improving approximate results by the aforementioned authors and by DeBiasio and Nelsen.
