Questions about extreme points

Abstract

We discuss the geometry of the unit ball -- specifically, the structure of its extreme points (if any) -- in subspaces of L1L^1 and LL^\infty on the circle that are formed by functions with prescribed spectral gaps. A similar issue is considered for kernels of Toeplitz operators in HH^\infty.
