A continuum dimensional algebra of nowhere differentiable functions

Classical Analysis and ODEs 2023-07-31 v2

Abstract

We construct an algebra of dimension 202^{\aleph_0} consisting only of functions which in no point possess a finite one-sided derivative. We further show that some well known nowhere differentiable functions generate algebras, which contain functions which are differentiable at some points, but where for all functions in the algebra the set of points of differentiability is quite small.
