| Abstract: | We organize the results of the upper bounds of Laplacian spectral radius for some graphs in the last few years and explore the upper bounds of Laplacian spectral radius for the Cartesian product of circulant graphs based on the eigenvalues of the Cartesian product of two graphs. Our results generalize and improve the conclusion of the existing literatures. |
