“…These attentions can be attributed to widely-used of fractional differential equations tools in many scientific fields such as chemistry, biology, physics, control theory, viscoelasticity, electrochemistry, signal processing, nuclear dynamics, etc; see [[1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13]]. In fact, both Sequential Fractional Differential Equations (SFDEs), and Impulsive Fractional Differential Equations (IFDEs), have received a great deal of attention from many authors see [ [14], [15], [16], [17]]. However, a new topic has been investigated by combining both SFDEs and IFDEs, which in turn produced ISFDEs to be a much wider case.…”
