Abstract: In this paper, some comments are presented for the paper by Ahmadian A. etc (Chaos, Solitons & Fractals 104 (2017) 68–76). The Caputo-type derivative is approximated by a linearization formula in the mentioned paper. However, our research shows that this approach is incorrect and some counterexamples are presented to verify our analysis.
