On the facial structure of the unit ball in a complex Banach space

The problem of providing a complete description of the facial structure of the unit ball in a symmetric complex Banach space has been studied for thirty years and has often seemed intractable. This talk will begin with a history of the problem and end with its solution. This represents joint work with Francisco Fernandez-Polo, Christopher Hoskin, and Antonio Peralta.
