Аннотация: In this paper we prove that local fractional derivatives of differentiable functions are integer-order derivative or zero operator. We demonstrate that the local fractional derivatives are limits of the left-sided Caputo fractional derivatives. The Caputo derivative of fractional order α of function f(x) is defined as a fractional integration of order n−α of the derivative f(n)(x) of integer order n . The requirement of the existence of integer-order derivatives allows us to conclude that the local fractional derivative cannot be considered as the best method to describe nowhere differentiable functions and fractal objects. We also prove that unviolated Leibniz rule cannot hold for derivatives of orders α≠1 . http://link.springer.com/article/10.1007%2Fs40819-015-0054-6
