标题： Gauss-Bonnet Braneworld Cosmology with Modified Induced Gravity on the Brane

摘要： 我们分析了在体空间中包含高斯-博内项的DGP引力的扩展模型以及膜上$f(R)$引力的背景宇宙学。我们研究了这种设置对晚期宇宙历史的影响。通过动力系统方法，我们研究了这种设置的宇宙学动力学，重点探讨了曲率效应的作用。最后，我们通过与最新观测数据的对比来约束模型的参数。 显示英文摘要

摘要： We analyze the background cosmology for an extension of the DGP gravity with Gauss-Bonnet term in the bulk and $f(R)$ gravity on the brane. We investigate implications of this setup on the late-time cosmic history. Within a dynamical system approach, we study cosmological dynamics of this setup focusing on the role played by curvature effects. Finally we constraint the parameters of the model by confrontation with recent observational data.
