中文摘要：

我们将研究大反弹宇宙模型并与天文观测资料作比较, 重点讨论宇宙加速膨胀问题, 宇宙微波背景辐射(CMB)非各向同性问题, 结构形成问题, 暗能量问题, 以及巧合问题(The coincidence problem)等, 并由此尝试建立一个能模拟真实宇宙的大反弹模型. 我们将通过对该模型在反弹点附近的演化特性的研究, 探索了解在大反弹奇点处究竟发生了什么样的物理过程. 我们还将研究由Seahra和Wesson所发现的大反弹模型解与一类5维拓扑黑洞解之间的同胚关系, 尝试寻找出它们之间的具体的坐标变换式, 并通过对该类5维拓扑黑洞的视界面的研究, 探索大反弹奇点的物理与几何特性. 通过与标准大爆炸宇宙模型比较, 我们期望这些研究将有助于说明自然界是否存在额外维以及我们的宇宙是起源于一次大爆炸, 还是起源于一次大反弹.

中文主题词： 宇宙模型; 额外维; 大爆炸; 大反弹
