论文摘要
我们在四个维度上提出了修改的高斯 - 骨网重，可容纳在爱因斯坦的一般重力理论中获得的平坦的新兴宇宙（EU），具有非线性状态方程。欧盟模型很有趣，它具有宇宙的其他观察到的特征。假定目前的宇宙从静态的爱因斯坦宇宙阶段出现出来，存在于无限的过去。为了获得平坦的欧盟模型，我们重建了模仿修改的$ f（g）$ - 重力（$ g $代表高斯式术语），毫无疑问。确定了F（g）重力的功能形式，该功能形式可容纳早期通货膨胀和晚期加速阶段。
We present modified Gauss-Bonnet gravity without matter in four dimensions which accommodates flat emergent universe (EU) obtained in Einstein's general theory of gravity with a non-linear equation of state. The EU model is interesting which is free from big-bang singularity with other observed features of the universe. It is assumed that the present universe emerged out from a static Einstein universe phase exists in the infinite past. To obtain a flat EU model we reconstructed mimetic modified $f(G)$-gravity ($G$ representing Gauss-Bonnet terms) without matter. The functional form of f(G)-gravity is determined which accommodates the early inflation and late accelerating phases without matter.
