摘要
通过研究Tensor乘积图与其谱之间的关系,得到Tensor乘积图是整谱图的条件,并由此获得了构造新的整谱图的方法,找到了一些新的整谱有向图.
In this paper, we obtain some sufficient condition for Tensor product graphs to be integral, by using the relations between the Tensor product graphs and their spectra. We also give a new method to construct integral directed graphs and find some new integral directed graphs.
