度至多为4的图中的诱导匹配

Induced matchings in graphs of degree at most 4

Viet Hang Nguyen

摘要:

证明了如果$G$是一个最大度至多为$4$的连通图,而$4$不是$C_{2,5}$,则$G$的强匹配数至少为$\frac{1}{9}n(G)$ .这个界是紧的,证明意味着一个多项式时间算法找到一个诱导匹配的大小。

英文摘要:

We show that if $G$ is a connected graph of maximum degree at most $4$, which is not $C_{2,5}$, then the strong matching number of $G$ is at least $\frac{1}{9}n(G)$. This bound is tight and the proof implies a polynomial time algorithm to find an induced matching of this size.
