摘要: We first prove that for a continuous function f(x) defined on an open interval, the Kolvankar-Gangal’s (or equivalently Chen-Yan-Zhang’s) local fractional derivative f(α)(x) is not continuous, and then it impossible KG exists everywhere interval satisfies ≠ 0 in same time. In addition, we give criterion of nonexistence non-differentiable functions. Furthermore, construct two simple nowhere differentiable functions (0, 1) they have no derivatives everywhere.
