非同构无符号Laplacian余谱图的构造

Constructing Non-isomorphic Signless Laplacian Cospectral Graphs

Supriyo Dutta

摘要:

在这篇文章中,我们生成的非同构和无符号的Lalacian余谱图的大家庭使用部分转置图。我们的建筑非常强大。当顶点数为$\le 8$时,利用部分转置可以生成大于$70\%$的非同构无符号Laplacian同谱图.我们还提出了许多例子的非同构无符号拉普拉斯共谱图。

英文摘要:

In this article, we generate large families of non-isomorphic and signless Lalacian cospectral graphs using partial transpose on graphs. Our constructions are significantly powerful. More than $70\%$ of non-isomorphic signless-Laplacian cospectral graphs can be generated with partial transpose when number of vertices is $\le 8$. We have also produced numerous examples of non-isomorphic signless Laplacian cospectral graphs.
