一个图G的二分是将它的顶点集划分为基数相同的两个部分。G的AK-二等分是G的一个二等分,使得每个部分的每个分支至多有k个顶点。Cui和Liu证明了每一个无爪三次图都含有一个2-二等分图。本文改进了这一结果,证明了每个无爪三次图都包含一个具有有限条单色边的2-二等分图,其中2-二等分图的单色边是连接2-二等分图同一部分的两个顶点的边.我们还证明了我们的界是最好的可能为所有的无爪三次简单图。
A bisection of a graphGis a partition of its vertex set into two parts of the same cardinality. Ak-bisection ofGis a bisection ofGsuch that every component of each part has at mostkvertices. Cui and Liu proved that every claw-free cubic graph contains a 2-bisection. In this paper, we improve this result showing that every claw-free cubic graph contains a 2-bisection with bounded number of monochromatic edges, where amonochromatic edgeof a 2-bisection is an edge connecting two vertices of the same part of the 2-bisection. We also prove that our bound is best possible for all claw-free cubic simple graphs.
