标题： Asymptotic Behaviour of Inhomogeneous String Cosmologies

摘要： 在非均匀轴子-稀释子宇宙学的晚期时间的渐近行为被研究。 此处考虑的时空具有两个阿贝尔类空性Killing向量。 这些时空演化趋向于包含引力辐射的各向异性宇宙。 此外，发现Weyl张量和反对称张量场强度具有剥离行为。 简要讨论了与预大爆炸场景的关系。 显示英文摘要

摘要： The asymptotic behaviour at late times of inhomogeneous axion-dilaton cosmologies is investigated. The space-times considered here admit two abelian space-like Killing vectors. These space-times evolve towards an anisotropic universe containing gravitational radiation. Furthermore, a peeling-off behaviour of the Weyl tensor and the antisymmetric tensor field strength is found. The relation to the pre-big-bang scenario is briefly discussed.
