论文摘要

如果$ g $中匹配的$ m $是无环的,那么如果一组$ g $的子图是$ m $的一组$ g $的$ g $。我们证明,每个具有$ n $顶点的图形,最多最高$δ$,并且没有孤立的顶点,都具有至少$(1-o(1-o(1))\ frac {6n} {Δ^2} {δ^2} $的无环匹配,我们可以解释如何在多物质元素中找到这样的无环匹配。

A matching $M$ in a graph $G$ is acyclic if the subgraph of $G$ induced by the set of vertices that are incident to an edge in $M$ is a forest. We prove that every graph with $n$ vertices, maximum degree at most $Δ$, and no isolated vertex, has an acyclic matching of size at least $(1-o(1))\frac{6n}{Δ^2},$ and we explain how to find such an acyclic matching in polynomial time.
