While preparing for the spectral graph theory boot camp, which starts this Tuesday at the Simons Institute, I collected the lecture notes of my class on graph partitioning and expanders in one file.
There are no references and, most likely, plenty of errors. If you use the notes and find mistakes, please let me know by either emailing luca at berkeley or leaving a comment here.

Thanks for the compilation. I’ll do my best to read it.
Thank you professor. I have been keeping all your lecture notes in one folder for quite a while. Your notes help clarify a lot of difficult points. I really appreciate that since I am learning all by myself and have no expert around to ask questions in Vietnam.
