摘要
根据原晋江在《导出匹配可扩图》一文中给出的图的导出匹配可扩性的概念,采用把图的任意匹配扩充为完美匹配的方法,研究了步长为1和(2n+1)/3的2n阶循环图的导出匹配可扩性,得出主要结论为:当n≥4时,步长为1和(2n+1)/3的2n阶循环图是导出匹配可扩的.
According to the result of Induced Matching Extendable Graph by Yuan Jinjiang, Using the method expending an arbitrary matching to a perfect matching, the paper investigates the induced matching extendendability of cyclic graph with 2n Vertices and step length 1 and (2n+1)/3. The main result is that, when n≥4, the cyclic graph with 2n Vertices and step length 1 and (2n+1)/3 is IM-extendable.
