Will the set of eigenvalues of an incident matrix derive an equivalent notion of a graph spectrum as it does with an adjacency matrix?(adsbygoogle = window.adsbygoogle || []).push({});

Specifically:

Letsbe the set of eigenvalues of an adjacency matrix for graph_{a}G.

And,

Letbe the set of eigenvalues of an incident matrix for graphs_{i}G.

What are the differences betweensand_{a}? Could these both be considered spectrums of the graph? If not, why?s_{i}

Thanks much!
