摘要

This paper deals with the existence and uniqueness of periodic solutions for a nonlinear fractional pantograph coupled system with \(\psi \) ψ -Caputo derivative. We employ the coincidence degree theory of Mawhin to established our proofs. An illustration will be presented to demonstrate the validity of the given result.
