Algebra Seminar: "Fun with Modular Forms: Moonshine and Black Holes" by Christoph Keller

Speaker: Christoph Keller, University of Arizona

The Fourier coefficients of modular objects have a long history of providing interesting mathematical insights. After a brief introduction to classical topics such as Eisenstein series, I will present two more modern developments. On the one hand I will discuss monstrous moonshine and its modern cousin, Mathieu moonshine. The key insight here is the relation of modular objects to vertex operator algebras. On the other hand I will discuss the relation of modular objects to the thermodynamics of black holes, and how the asymptotic growth of their Fourier coefficients is crucial for describing them.
