论文摘要
我们在考虑不同的空间曲率值的同时，提出了具有球形对称性的Stephani溶液的特殊情况。我们研究了模型中宇宙演化的动力学，为所得时空构建R-T区域并分析减速参数的行为。还讨论了模型的奇异性。探索了所获得溶液的空间部分的几何形状。
We present a special case of the Stephani solution with spherical symmetry while considering different values of spatial curvature. We investigate the dynamics of the universe evolution in our model, build the R--T-regions for the resulting spacetime and analyze the behavior of the deceleration parameter. The singularities of the model are also discussed. The geometry of the spatial part of the obtained solution is explored.
