    Relaxation Oscillation in SEIR Epidemic Models with the Intrinsic Growth Rate by Yingying Zhang, Ruohan Wang, Yanan Cai

    Published 2024-01-01
    “…In this study, to further reveal the mathematical mechanism of spontaneous generation of periodic oscillation solution, we investigate a type of SEIR epidemic model with a small intrinsic growth rate. By utilizing the singular perturbation theory and center manifold theorem, we extend the relaxation oscillation of three-dimensional SIR models to the four-dimensional SEIR models and prove the existence of stable relaxation oscillation with a large amplitude in the model. …”
