论文摘要
我们以高斯式术语构建模型乘以标量场的函数，从而导致通货膨胀情况。考虑因素与慢速近似有关。宇宙吸引子方法给出了标量扰动的频谱指数，这与现代观察值非常吻合，并允许张量与尺度比率变化。我们重建具有参数可变性的模型，这些模型允许在爱因斯坦 - 高斯 - 邦纳特重力中以$ 1/n $近似为$ 1/n $近似的通货膨胀参数的宇宙吸引者预测。
We construct models with the Gauss-Bonnet term multiplied to a function of the scalar field leading to inflationary scenario. The consideration is related with the slow-roll approximation. The cosmological attractor approach gives the spectral index of scalar perturbations which is in a good agreement with modern observation and allows variability for tensor-to-scalar ratio. We reconstruct models with variability of parameters which allow to reproduce cosmological attractor predictions for inflationary parameters in the leading order of $1/N$ approximation in the Einstein-Gauss-Bonnet gravity.
