Chain rule for pointwise Lipschitz mappings

Jan Kolář, Olga Maleva

The classical Chain Rule formula gives the (partial, or directional) derivative of the composition of mappings and . We show how to get r…

Extreme non-differentiability of typical Lipschitz mappings

Michael Dymond, Olga Maleva

We show that no matter what subset of a normed space is given, a typical 1-Lipschitz mapping into a Banach space is non-differentiable at a typical point of the set in a very stron…

On the structural decomposition of planar Lipschitz quotient mappings

Ricky Hutchins, Olga Maleva

We show that for each fixed non-constant complex polynomial of the plane there exists a homeomorphism such that is a Lipschitz quotient mapping. This corrects er…

Typical Lipschitz mappings are typically non-differentiable

Michael Dymond, Olga Maleva

We prove that a typical Lipschitz mapping between any two Banach spaces is non-differentiable at typical points of any given subset of its domain in the most extreme form. This is…

A dichotomy of sets via typical differentiability

Michael Dymond, Olga Maleva

We obtain a criterion for an analytic subset of a Euclidean space to contain points of differentiability of a typical Lipschitz function, namely, that it cannot be covered by count…

Cone unrectifiable sets and non-differentiability of Lipschitz functions

Olga Maleva, David Preiss

We provide sufficient conditions for a set to be a non-universal differentiability set, i.e. to be contained in the set of points of non-differentiability of…
