| Jul 22, 2021 at 3:37 | comment | added | Lars | I have added an edit to my response. I believe corollary 23 of the referenced paper states that any continuous function of finite quadratic variation with only countably many nondifferentiable points has quadratic variation zero. If this is indeed what it says then the answer to this question is affirmative. | |
