标题： Gravitation and cosmology in a brane-universe

摘要： 近期理论发展激发了对“膜世界”图景的极大兴趣，该图景假设普通物质被限制在一个三维子流形上，通常称为“膜”，嵌入到更高维的空间中。本文综述的目的在于介绍这类模型中有关引力的一些基本结果，然后呈现膜宇宙学的各个方面。 显示英文摘要

摘要： Recent theoretical developments have generated a strong interest in the ``brane-world'' picture, which assumes that ordinary matter is trapped in a three-dimensional submanifold, usually called brane, embedded in a higher dimensional space. The purpose of this review is to introduce some basic results concerning gravity in these models and then to present various aspects of the cosmology in a brane-universe.
