报告题目：The existence of periodic solutions for discrete-time coupled systems on networks with time-varying delay

报告摘要：This talk deals with the existence of periodic solutions for discrete-time coupled systems on networks with time-varying delay (DCSNTD). Based on coincidence degree theory, graph theory, and Lyapunov method, a systematic method is given to study the existence of periodic solutions for DCSNTD. A Lyapunov-type theorem and a coefficient-type criterion are derived, respectively. Furthermore, we apply this novel approach to research the existence of periodic solutions for discrete-time coupled oscillators with time-varying delay. Finally, a numerical simulation is presented to illustrate the effectiveness and feasibility of our results.
