给出了无限、半无限和有限莫尔斯流线空间紧化上的角结构流形和结合胶合映射的初等构造。在欧氏度量的情况下,在莫尔斯坐标附近的每个临界点,这些自然是由端点和定期水平集的评估。对于有限端,这需要在临界点结束的轨迹附近进行爆破构造。
We give elementary constructions of manifold with corner structures and associative gluing maps on compactifications of spaces of infinite, half infinite and finite Morse flow lines. In the case of Euclidean metric in Morse coordinates near each critical point, these are naturally given by evaluations at end points and regular level sets. For finite ends this requires a blowup construction near trajectories ending at critical points.
