关于三次图的不交匹配

On disjoint matchings in cubic graphs

Vahan V. Mkrtchyan, Samvel S. Petrosyan, Gagik N. Vardanyan

摘要:

对于$i=2,3$和三次图$G$,让$ν_{i}(G)$表示$i$匹配可以覆盖的最大边数。我们发现,$ν_{2}(G)\geq {4/5}| V(G)| $和$ν_{3}(G)\geq {7/6}| V(G)| $。此外,事实证明,$ν_{2}(G)\leq \frac{|V(G)|+2ν_{3}(G)}{4}$。

英文摘要:

For $i=2,3$ and a cubic graph $G$ let $ν_{i}(G)$ denote the maximum number of edges that can be covered by $i$ matchings. We show that $ν_{2}(G)\geq {4/5}| V(G)| $ and $ν_{3}(G)\geq {7/6}| V(G)| $. Moreover, it turns out that $ν_{2}(G)\leq \frac{|V(G)|+2ν_{3}(G)}{4}$.
