摘要:
我们利用不依赖时间的不完备哈密顿流,从辛流形中切除具有正余维数的有意义闭子集。这类子集的例子包括我们所称的“康托尔刷”、“带尾盒子”,以及更一般的下半连续函数的上方图。这解答了Alan Weinstein提出的关于射线切除的问题,并推广了Bernd Stratmann关于射线与流形乘积的切除结果。
英文摘要:
We use time-independent incomplete Hamiltonian flows to excise interesting closed subsets of positive codimension from symplectic manifolds. Examples of such subsets include what we call a "Cantor brush", a "box with a tail", and -- more generally -- epigraphs of lower semicontinuous functions. This answers a question of Alan Weinstein about excision of a ray, and it generalizes a result of Bernd Stratmann about excision of the product of a ray with a manifold.
