[EN] In this paper, we present some sufficient conditions on a metric space M for which every molecule is a strongly subdifferentiable (SSD, for short) point in the Lipschitz- free space F(M) over M. Our main result reads ...
[EN] We consider convex series of molecules in Lipschitz-free spaces, i.e. elements of the form such that . We characterise these elements in terms of geometric conditions on the points , of the underlying metric space, ...
