dc.description.abstractWe discuss the geometry of the unit ball —specifically, the structure of its extreme points (if any)— in subspaces of $L^{1}$ and $L^{\infty}$ on the circle that are formed by functions with prescribed spectral gaps. A similar issue is considered for kernels of Toeplitz operators in $H^{\infty}$.
