To describe a late stage in the evolution of the universe, we consider a low energy density dust-filled 4-dimensional brane, immersed in a 5-dimensional space-time. Assuming that cosmological dynamics is governed by the Einstein–Gauss–Bonnet gravity field equations, we find a solution that exhibits an accelerated exponential behavior, which corresponds to a De Sitter model of universe.

5维Einstein-Gauss-Bonnet引力中的De Sitter膜世界解

为了描述宇宙演化的后期阶段，我们考虑了一个低能量密度、充满尘埃的 4 维膜，它沉浸在 5 维时空中。假设宇宙动力学受爱因斯坦-高斯-博内引力场方程的支配，我们找到了一个表现出加速指数行为的解，这对应于宇宙的德西特模型。
