Resumen de Supports and extreme points in Lipschitz-free spaces

Ramón J. Aliaga, Eva Pernecká

• For a complete metric space M, we prove that the finitely supported extreme points of the unit ball of the Lipschitz-free space FM are precisely the elementary molecules (δ(p)−δ(q))/d(p,q) defined by pairs of points p,q in M such that the triangle inequality d(p,q)
