The Clay Mathematics Institute (CMI) is dedicated to increasing and disseminating mathematical knowledge. Since 1999, the CMI/PROMYS partnership has run the research labs and the advanced seminars.

In 2017, for the further enrichment of our returning students and counselors, PROMYS and the Clay Mathematics Institute will offer advanced seminars in The Analytic Class Number Formula, Algebra, and Geometry and Symmetry.

Past seminars have included: Values of the Zeta Function and p-Adic Analysis, Modular Forms, Complex Analysis in Number Theory, Combinatorics, Values of the Riemann Zeta Function, Abstract Algebra, Modular Forms, Hyperbolic Geometry, Random Walks on Groups, Dirichlet Series, Graphs and Knots, The Mathematics of Algorithms, and Character Sums.

Professor Jared Weinstein, Boston University

We know that some number systems like Z[i] have the property of unique factorization, while others such as Z[sqrt{-5}] fall short of it. The "class number" is a measure of how close a number system is to having this property. We will investigate some surprising formulas for the class number in terms of infinite series. Our goal will be to cover Kummer's proof of Fermat's Last Theorem for so called "regular primes".

Professor Marjory Baruch, Syracuse University

In the PROMYS style, we will be exploring abstract algebraic structures as they arise from concrete examples. We will learn about groups in the context of permutations, symmetries, and transformations. We will look at some classical results, possibly including issues of solving a fifth degree equation, tessellations of the plane and higher dimensions, and writing down roots of third degree equations. Number theory and counting will be used throughout, as will geometry. For those interested, there will be opportunities to model some of what we are doing on the computer.

Professor Steven Rosenberg, Boston University

Besides the standard high school geometry, there are geometries of finite sets of points and lines, non-Euclidean geometries, and geometries of shortest paths on bumpy surfaces (like the earth's surface). Each geometry has its group of symmetries – the functions from the points of the geometry to the points that preserve the geometric structure. Properties of this group of symmetries explain many deep features of the geometry. We will discuss the classical geometries of Euclidean, spherical, projective and hyperbolic type and develop the group theory techniques needed to understand their symmetry groups. We will also relate area and volume to matrix groups and linear algebra. Finally, we will use properties of the symmetry groups of Euclidean space to study paradoxical decomposition of spheres.
