对于两个图G和H,冠积是将G的一个副本和H的副本,并将G的第i个顶点与H的第i个副本的每个顶点连接而得到的图。本文研究了日冕相对于无符号拉普拉斯矩阵的状态转移。我们探讨了保证无符号拉普拉斯完美态转移的条件。我们证明了对于某些特殊的m,不存在无符号的Laplacian完美状态转移。对于正则图H,我们还证明了相对于无符号拉普拉斯矩阵,它有很好的状态转移,但没有完美的状态转移。此外,我们还证明了无符号Laplacian很好的状态转移,鸡尾酒会图在哪里。
For two graphs G and H, the corona product is the graph obtained by taking one copy of G and copies of H, and joining the ith vertex of G with every vertex of the ith copy of H. In this paper, we study the state transfer of corona relative to the signless Laplacian matrix. We explore some conditions that guarantee the signless Laplacian perfect state transfer in . We prove that has no signless Laplacian perfect state transfer for some special m. We also show that has pretty good state transfer but no perfect state transfer relative to the signless Laplacian matrix for a regular graph H. Furthermore, we show that has signless Laplacian pretty good state transfer, where is the cocktail party graph.
