1) lexicographic product
字典积
1.
Flows on lexicographic product of graphs;
图的字典积的整数流(英文)
2.
Structure,nullity and rank of strongly regular graphs under certain binary operation-lexicographic product was discussed,and some meaningful results were obtained in this paper.
设G,H是两个强正则图,它们的字典积(lexicographic product)图的零度和秩是指它们的邻接矩阵的零度和秩。
3.
In this paper,we characterize graphs whose lexicographic product admits nowhere-zero 3-flow.
充分利用图的字典积的结构证明了以下结论:如果图G_1的每连通分支都非平凡,图G_2的阶数大于3,那么它们的字典积G_1[G_2]具有非零3-流。

4) generalized lexicographic product
广义字典序积
1.
The endomorphism monoids of the generalized lexicographic product of graphs;
广义字典序积的自同态幺半群
2.
Unretractive property of generalized lexicographic product of graphs;
图的广义字典序积的不可收缩性
3.
Strong unretractive property of generalized lexicographic product of graphs is discussed.
通过对图的广义字典序积的强不可缩回性的讨论 ,得到了如下结果 :若对每个x∈V(X) ,图Yx 是非平凡的连通图 ,则X[Yx x∈V(X) ]是强不可缩回的充要条件是每个Yx 都是强不可缩回的 ;若对每个x∈V(X) ,图Yx 有两个连通分支 ,其中恰有一个分支是孤立点 ,则X[Yx x∈V(X) ]是强不可缩回的充要条件是每个Yx 及X都是强不可缩回的 。
