*q*‐fractional differential equations involving integral boundary conditions associated with Stieltjes integral and its corresponding coupled system. We are using some sufficient conditions to achieve the existence and uniqueness results for the given problems by applying the Banach contraction principle, Schaefer's fixed point theorem, and Leray–Schauder...

*N*-coupled fractional-order chaotic systems with ring connection via bidirectional coupling. On the basis of the direct design method, we design the appropriate controllers to transform the fractional-order error dynamical system into a nonlinear system with antisymmetric structure. By choosing appropriate fractional-order Lyapunov functions and employing...
