ABSTRACT
For a simple connected graph G of order n, we obtain the distance signless Laplacian spectrum of the joined union of regular graphs in terms of their adjacency spectrum and the spectrum of an auxiliary matrix. As a consequence, we obtain the distance signless Laplacian spectrum of the zero divisor graphs of finite commutative rings for some values of n. We show that is not in general distance signless Laplacian integral for , where p is any prime and Also, we find the spectrum of for certain values of z.

摘要
对于一个简单的n阶连通图G,我们得到了正则图联合并集的距离无符号拉普拉斯谱根据它们的邻接谱和辅助矩阵的谱。因此,我们获得了有限交换环的零因数图的距离无符号拉普拉斯谱对于n的某些值。我们表明不是一般距离无符号拉普拉斯积分, 其中p是任意素数并且此外,我们发现频谱对于z的某些值。
