It is shown that the generalized Collins–Stewart radiation and Milne solutions are attractors of the massless Einstein–Vlasov system for Bianchi types II and V spacetimes, respectively. The proof is based on an energy method and bootstrap argument which are used to determine the decay rates of the perturbations away from the attractors.

具有无质量弗拉索夫物质的Bianchi II和V型宇宙学的未来吸引子

结果表明，广义的Collins–Stewart辐射和Milne解分别是Bianchi II型和V型时空的无质量Einstein-Vlasov系统的吸引子。证明基于能量方法和自举参数，用于确定远离吸引子的扰动的衰减率。
