摘要：
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) and (w) over tilde (i)(j)(w) over tilde (j)(i) as O(t(-1/2)).
