Spectral Heuristics Applied to Vertex Reliability

Carla Silva Oliveira, Fausto Marques Pinheiro Junior, Jose Andre de Moura Brito

The operability of a network concerns its ability to remain operational, despite possible failures in its links or equipment. One may model the network through a graph to evaluate…

On the characteristic polynomial of the $A_{α}$ -matrix for some operations of graphs

João Domingos G. da Silva, Carla Silva Oliveira, Liliana Manuela G. C. da Costa

Let G be a graph of order $n$ with adjacency matrix $A (G)$ and diagonal matrix of degree $D (G)$ . For every $α \in [0, 1]$ , Nikiforov \cite{VN17} defined the matrix $A_α(G) = αD(G) +…
