Effects of asymmetric coupling and boundary on the dynamic behaviors of a random nearest neighbor coupled system

This study investigates the dynamical behaviors of nearest neighbor asymmetric coupled systems in a confined space.First,the study derivative analytical stability and synchronization conditions for the asymmetrically coupled system in an unconfined space,which are then validated through numerical simulations.Simulation results show that asymmetric coupling has a significant impact on synchronization conditions.Moreover,it is observed that irrespective of whether the system is confined,an increase in coupling asymmetry leads to a hastened synchronization pace.Additionally,the study examines the effects of boundaries on the system's collective behaviors via numerical experiments.The presence of bound-aries ensures the system's stability and synchronization,and reducing these boundaries can expedite the synchronization process and amplify its effects.Finally,the study reveals that the system's output amplitude exhibits stochastic resonance as the confined boundary size increases.
