“…Because, non-integer order differential equations have many applications in various branches of science and engineering such as signal processing, viscoelasticity, biology, physics, chemistry, control theory and stability of networking and modeling of biological phenomenons, etc., for detail see [6,13,14,16,18]. The qualitative theory devoted to existence of solutions to non-integer order differential equations involving boundary conditions has been an active area of research for the last few decades.…”
