**About this course**: A central focus of this course will be to uncover properties of Boolean functions via analytic methods (such as studying their Fourier spectrum). Such methods have seen remarkable applications in various fields of theoretical computer science such as property testing, hardness of approximation, learning theory, pseudorandomness, etc, and is by now an essential ingredient in a theorist's toolkit. These methods have also found nice applications beyond computer science, in areas such as combinatorics, random graphs and metric spaces. We will develop this theory from the basics and cover a variety of applications in the course.
**Prerequisites:** CS 4820 or permission from the instructor. In general, some mathematical maturity is expected. Familiarity with basic notions of algebra (such as finite fields, basics of vector spaces, polynomials), linear algebra, discrete probability, and basics of computational complexity theory will come in handy.
