    Anomaly induced inflation in the minimal quartic extension of Einstein’s gravity by Kerim Demirel, Bayram Tekin

    Published 2024-12-01
    “…We study the inflation phase of the universe in this minimal quartic extension of Einstein’s gravity in the presence of trace anomaly terms coming from the Standard Model fields and the fields of the Minimal Supersymmetric Standard Model. We show that the theory allows a quasi-de Sitter phase with sufficient e-foldings.…”

    Sensitivities in Models with Backward Dynamics by Yonghong Chen, Xunxiang Guo

    Published 2019-01-01
    “…We mainly introduce the concept of P-sensitivity and P-Li-Yorke sensitivity especially for the multivalued forward dynamics of such models and characterize P-sensitivity and P-Li-Yorke sensitivity of the multivalued forward dynamics in terms of sensitivity and Li-Yorke sensitivity of an induced single-valued dynamics by using the theory of inverse limits. Similarly, we also characterize the sensitivity and Li-Yorke sensitivity of the single-valued backward dynamics of such models in terms of the corresponding sensitivities of an induced single-valued dynamics.…”
