Spectra and Laplacian spectra of arbitrary powers of lexicographic products of graphs

Nair Abreu, Domingos M. Cardoso, Paula Carvalho +1

Consider two graphs $G$ and $H$. Let $H^k[G]$ be the lexicographic product of $H^k$ and $G$, where $H^k$ is the lexicographic product of the graph $H$ by itself $k$ times. In this…
