\(c_0\) is isometrically isomorphic to a subspace of Cantor-Lebesgue functions (Q2257691)

The author proves that \(c_0\) is isometrically isomorphic to a subspace of continuous almost everywhere differentiable functions on the real interval \([0,1]\) with almost everywhere null derivative and that are non-Lipschitz. This improves a result on the lineability of this set of functions stated in [\textit{P. Jiménez-Rodríguez} et al., Linear Algebra Appl. 437, No. 4, 1174--1181 (2012; Zbl 1267.46037)].
