### Twenty examples of AAA approximation

## Abstract

For the first time, a method has become available for fast computation of near-best rational approximations on arbitrary sets in the real line or complex plane: the AAA algorithm (Nakatsukasa-Sète-T. 2018). After a brief presentation of the algorithm this talk will focus on sixteen demonstrations of the kinds of things we can do, all across applied mathematics, with a black-box rational approximation tool.
