Title:

Finite frames and optimal subspace packings

Abstract:

John Benedetto is a fantastic advisor, with a knack for posing problems that a student can build a career on. For me in particular, John's questions led to a lifelong exploration of finite frames and their connections to optimal packings in Grassmannians, including equiangular tight frames. I'll present an overview of these connections, with an emphasis on historical developments, the current state-of-the-art, and important open problems.
