We show that massless solutions to the Einstein–Vlasov system in a Bianchi I space-time with small anisotropy, i.e. small shear and small trace-free part of the spatial energy momentum tensor, tend to a radiation fluid in an Einstein–de Sitter space-time with the anisotropy $$\Sigma ^a_b\Sigma ^b_a$$ Σ b a Σ a b and $$\tilde{w}^i_j \tilde{w}^j_i$$ w ~ j i w ~ i j decaying as $$O(t^{-\frac{1}{2}})$$ O ( t - 1 2 ) .

关于 Bianchi I 宇宙学中无质量爱因斯坦-弗拉索夫系统的未来解决方案

我们表明,在比安奇 I 时空中,爱因斯坦-弗拉索夫系统的无质量解具有小各向异性,即空间能量动量张量的小剪切和小无迹部分,倾向于爱因斯坦-德西特空间中的辐射流体-时间与各向异性 $$\Sigma ^a_b\Sigma ^b_a$$ Σ ba Σ ab 和 $$\tilde{w}^i_j \tilde{w}^j_i$$ w ~ jiw ~ ij 衰减为 $$O (t^{-\frac{1}{2}})$$ O ( t - 1 2 ) 。
