论文摘要
我们认为Kasner时空描述了流体的各向异性三维膨胀，并从动力学理论中获得了剪切应力张量和能量密度的耗散演化方程。为此，我们使用相对论玻尔兹曼方程的迭代解决方案，并使用松弛时间近似。我们表明，在适当的科斯纳时空参数的适当条件下，我们的第二和三阶进化方程将其结果减少到一维扩张案例的结果。
We consider Kasner space-time describing anisotropic three dimensional expansion of the fluid and obtain the dissipative evolution equations for shear stress tensor and energy density from kinetic theory. For this, we use the iterative solution of relativistic Boltzmann equation with relaxation time approximation. We show that our results for second and third order evolution equations reduce to those of one dimensional expansion case under suitable conditions for the anisotropic parameters in Kasner space-time.
