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…

Injective Edge Chromatic Index of a Graph

Domingos M. Cardoso, J. Orestes Cerdeira, J. Pedro Cruz +1

Three edges $e_{1}, e_{2}$ and $e_{3}$ in a graph $G$ are consecutive if they form a path (in this order) or a cycle of length three. An injective edge coloring of a graph $G = (V,…
