紧度量空间上Lipschitz自由空间的极值点

Extreme points in Lipschitz-free spaces over compact metric spaces

Ramón J. Aliaga

摘要:

证明了紧致度量空间上Lipschitz-free空间的单位球的所有极值点都有有限支撑.结合已有的结果,这完全刻画了双对偶球上的极值点,并暗示它们也都是双对偶球上的极值点。为了证明这一点,我们发展了最初由K给出的Lipschitz空间上泛函的整表示的一些性质。de Leeuw。

英文摘要:

We prove that all extreme points of the unit ball of a Lipschitz-free space over a compact metric space have finite support. Combined with previous results, this completely characterizes extreme points and implies that all of them are also extreme points in the bidual ball. For the proof, we develop some properties of an integral representation of functionals on Lipschitz spaces originally due to K. de Leeuw.
