In this paper, we present results on the existence, uniqueness, and Ulam–Hyers–Mittag-
Leffler stability of solutions to a class of ψ-Hilfer fractional-order delay differential equations …

In this paper, we study a nonlinear fractional q-difference equation with nonlocal boundary
conditions. The existence of solutions for the problem is shown by applying some well …

This paper considers the tracking control of fractional-order nonlinear systems (FONSs) in
triangular form with actuator faults by means of sliding mode control (SMC) and composite …

In this paper, different height functions of the nonlinear term on special bounded sets
together with Leggett–Williams and Krasnosel'skii fixed point theorems are employed to …

In this paper, we focus on the convergence analysis and error estimation for the unique
