关于一点联的Cordial性的一个结果的推广

A Promoted Result on the Cordiality of the One-point Union

将文献[2](Shee S C,Ho Y S.The Cordiality of One-point Union of n-copies of a Graph.Discrete Math,1993,117:225-243)的结果推广到一般的圈的一点联,即粘连的圈的个数是任意的且每个圈的顶点数也是任意的情况,并给出了此类一点联的Cordial性的分析证明.

A promoted result of [2]（Shee S C, Ho Y S. The Cordiality of One-point Union of n-copies of a Graph. Discrete Math, 1993,117：225-243） on the cordiality of the one-point union is presented, i.e. the number of the cycles and the number of the vertices on each cycle are arbitrary. An analytical proof on its cordiality is proposed.
