## Math 471: Mathematics of Aperiodic Order

**Course Description**:

The mathematics of aperiodic order is a very young mathematical discipline, which arose from the discovery of quasicrystals in the early 1980's. The physical motivation is the introduction and study of mathematical models of quasicrystals. Independently of the relevance to physics and more generally, one is interested in features of order in the absence of periodicity. The resulting mathematics is rich and fascinating, and it touches upon a number of established areas such as discrete geometry, harmonic analysis, combinatorics, spectral theory, and many more. In this course we will take an example-based approach and explore order features of structures such as Penrose and related tilings, which will guide us towards more general structures generated by inflation or a cut-and-project scheme. This course should be accessible to all interested students who have had some prior exposure to proof-based mathematics on the level of Math 3xx courses.

**Grades**:

The final grade for the course will be based on your homework scores.

**Homework**:

There will be weekly homework assignments with due date indicated on each problem set. These assignments will be accessible through OWL-Space. The homework is not pledged. You are encouraged to discuss the homework, and to work together on the problems. However, each student is responsible for the final preparation of his or her own homework papers.
