Comment for Existence and Hyers-Ulam stability for a nonlinear singular fractional differential equations with Mittag-Leffler kernel

In a published paper of Journal of Chaos, Solitons and Fractals, some miss prints were found. One is about the calculation of the solution and also about the expression of the solution using Green's function of the fractional differential equation studied in this paper; The others are for the properties for Green's function, these miss prints affected the deriving of the main results in Khan's paper, some corrections for Khan's paper should be needed. In this paper, we make some corrections and give the correct proof proceeding for the results, a new example is given to validate part of the proven results. (C) 2020 Elsevier Ltd.
