On construit une famille de fonctions continues sur l’intervalle qui n’a nulle part de dérivée unilatérale finie ou infinie utilisant les équations fonctionnelles de De Rham. Puis on démontre que, pour tout , il existe une dans toute classe lipschitzienne d’ordre inférieur à 1 tel que la mesure de l’ensemble de nœud points de est égale à .
We construct a family of continuous functions on the unit interval which have nowhere a unilateral derivative finite or infinite by using De Rham’s functional equations. Then we show that for any there exists an in any Lipschitz class of order less than one such that the set of knot points of has a measure .
