Math 521: Advanced Topics in Real Analysis - Ergodic Schrödinger Operators

Course Description:
We will present the general theory of ergodic Schrödinger operators, including almost sure invariance of spectra and spectral types, the definition and general properties of the integrated density of states and the Lyapunov exponent, and Kotani theory. Quasi-periodic and random operators will be studied in detail. Operators generated by other underlying dynamics, such as the skew-shift and the doubling map, will also be discussed. There are no required prerequisites, though familiarity with linear algebra, probability theory, basic real and complex analysis, and some functional analysis will be helpful.

60% Homework
40% Presentation of a Research Paper

There will be regular homework assignments. All homework should be turned in during class on or before the due date. The homework is not pledged. You are encouraged to discuss the homework and to work together on the problems, though you should write up your own submission.

Each student will be asked to give a public presentation of a fundamental research paper in the field. The instructor will recommend a number of papers, but other suggestions are welcome.

Disabilities Statement:
Any student with a documented disability needing academic adjustments or accommodations should speak to me as soon as possible, preferably during the first two weeks of class. I will be happy to help you, and all communications will remain confidential. As a reminder, you will also need to contact Disability Support Services in the Ley Student Center ( If you believe that you have an undocumented disability, you are encouraged to talk to me and Disability Support Services so that you can get help.
