> No one represents graphs as matrices in computer science, and graph theorists rarely touch representation theory. Are you conflating linear algebra and representation theory, or did you really mean to refer to representation theory in particular? The notion of a quiver (https://en.wikipedia.org/wiki/Quiver_(mathematics) https://en.wikipedia.org/wiki/Quiver_(mathematics) ) seems to me to be a unification of the two fields; I'm not a graph theorist, but I have a hard time imagining that they don't at least consider these structures.
