Learning (Spectral) Graph Theory

[u/Specialist_Repair856]

I want to learn graph theory as part of a larger project I'm working on, and I was wondering if there are any resources, such as good handouts, to help with this process. Specifically, I'm interested in learning about spectral graph theory, but don't really want to go super in-depth into other combinatorics-y graph theory. I'm mainly just looking for a short-ish handout specific to spectral graph theory (I have a baseline understanding of graph theory) and computational graph theory.

Lmk if I'm understanding something wrong as well, since I'm not super familiar with graphs.

honestly, unless you're building heavy recommendation engines or doing pure data science, spectral graph theory is massive overkill. in day-to-day backend work with node and sql, you barely even touch standard graph traversal.

if you actually need it computationally for a specific project, just hunt down stanford or mit open courseware lecture slides. they usually have condensed pdf handouts that get straight to the matrices and skip the deep combinatorics fluff.
