摘要

摘要本文根据原始图的归一化拉普拉斯特征值，确定了具有任意正则图的连通正则图的Q顶点电晕、Q边电晕、Q顶点邻域电晕和Q边邻域电晕的归一化拉普拉斯谱。此外，应用这些结果，我们发现了一些非正则归一化拉普拉斯共谱图。

Normalized Laplacian Spectrum of Some Q-Coronas of Two Regular Graphs

Abstract In this paper we determine the normalized Laplacian spectrum of the Q-vertex corona, Q-edge corona, Q-vertex neighborhood corona, and Q-edge neighborhood corona of a connected regular graph with an arbitrary regular graph in terms of normalized Laplacian eigenvalues of the original graphs. Moreover, applying these results we find some non-regular normalized Laplacian co-spectral graphs.
