ABSTRACT
This paper presents a critical analysis of a numerical technique that has been used in the resolution of fractional differential equations with Caputo derivative. It is the multi-step method with generalized differential transform. It is found that the version of the method available in the literature produces erroneous solutions from the second step, this is shown in applications to the Malthus and Riccati models. The procedure error is explained in terms of the nonlocality of the Caputo derivative and the properties of the generalized differential transform.
