摘要

This study focuses on developing novel criteria for assessing the stability of nonlinear incommensurate fractional-order difference systems (FoDS), modeled using the Caputo difference operator. The proposed criteria are supported by rigorous proofs utilizing the Lyapunov function method. The theoretical findings are verified through numerical simulations, demonstrating stability in the considered systems.
