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((alpha))(x) is not continuous, and then prove that it is impossible that the KG derivative f ((alpha))(x) exists everywhere on the interval and satisfies f((alpha))(x) not equal 0 in the same time. In addition, we give a criterion of the nonexistence of the local fractional derivative of everywhere non-differentiable continuous functions. Furthermore, we construct two simple nowhere differentiable continuous functions on (0, 1) and prove that they have no the local fractional derivatives everywhere. (C) 2016 Elsevier B.V.
