Points of differentiability of the norm in Lipschitz-free spaces

Ramón J. Aliaga, Abraham Rueda Zoca

We consider convex series of molecules in Lipschitz-free spaces, i.e. elements of the form $\mu ={\sum }_n{\lambda }_n\frac{{\delta }_{x_n}-{\delta }_{y_n}}{d(x_n,y_n)}$ such that $\Vert \mu \Vert ={\sum }_n|{\lambda }_n|$. We cha…
