Spectral Graph Theory, Fall 2015

The first lecture will be on the 3rd floor of 17 Hillhouse
AMTH 561/CPSC 662, is a graduate course on Spectral Graph Theory and related topics. It will be taught in the style of a math class. I will present a bunch of theorems, a few algorithms, and many open problems. I have chosen to only present material that I consider beautiful. My other goals are to present material that is useful and to introduce fundamental concepts. The obvious prerequisites for this course are knowledge of linear algebra and exposure to graph theory. The less obvious requirement are "mathematical maturity" and "mathematical literacy". I will sometimes make use of concepts that every graduate student in Mathematics should know. I assume that students who are not familiar with these can look them up. A few that I will use are: I will teach a lot of linear algebra during this course. You could think of this as a graduate course in linear algebra.


There will be 5 or 6 problem sets, and no tests or exams. You may collaborate in small groups on the problem sets. Some of the problems will be hard. The problems sets and related announcements will be distributed via Classes V2.

I will occasionally include material in my lecture notes that I will not have time to cover in class. You are responsible for that material.


I will not assign a book for this course. Rather, I will produce notes for all the lectures.

Should you take this course?

You can get a good feel for what this course will be like by looking at the lecture notes from previous years. Here are the notes from 2012, 2009, and 2004. You should take this course if you This course is suitable for some advanced undergraduates. But, I warn them that it will move at a fast pace and will not be nearly as friendly as a typical undergrad course.

You can find the list of lectures I anticipate teaching on the course homepage.
