论文摘要
在Finslerian宇宙学模型的框架内考虑了宇宙的密度扰动，其中宇宙的背景时空被视为带有Finslerian扰动的空间平坦的FLRW时空。考虑到$（α，β）$ - 芬斯勒在宇宙的背景时空的$（α，β）$ - 芬斯勒空间中的重力的情况下，自然出现了物质（能量）密度的不均匀性。由此产生的不均匀物质密度表明物质扰动偏离了均匀的密度，这是由于riemannian时空中的Finslerian扰动引起的，从而确定了物质扰动的生长的几何起源。
The density perturbation of the universe has been considered in the framework of a Finslerian cosmological model in which the background spacetime of the universe is taken as the spatially flat FLRW spacetime with a Finslerian perturbation. The inhomogeneity in the matter(energy) density arises naturally in this consideration of gravity in the $( α, β)$ - Finsler space for the background spacetime of the universe. The resulting inhomogeneous matter density indicates matter perturbation departing from the uniform density, and it is caused by the Finslerian perturbation in the Riemannian spacetime, thus ascertaining the geometrical origin of the growth of matter perturbation.
