Comments on 'New approximations for solving the Caputo-type fractional partial differential equations'

摘要

In this paper, some comments are presented to the paper [J. Ren, Z. Sun, W. Dai, New Approximations for Solving the Caputo-Type Fractional Partial Differential Equations, Applied Mathematical Modelling (2015), doi: 10.1016/j.apm.2015.10.011]. A counterexample is taken to verify our analysis. As many papers have the similar mistake, it is very necessary to point out this error.
