连通n-流形上的纤维连通不定Morse 2-函数

Fiber connected, indefinite Morse 2-functions on connected n-manifolds

David T. Gay, Robion Kirby

摘要:

我们讨论了从光滑流形到光滑曲面的一般光滑映射,我们称之为“Morse 2-函数”,以及这些映射之间的同伦。两个中心问题是保持纤维连接,在这种情况下,莫尔斯2-函数是“纤维连接”,并避免局部极值超过1维子流形的范围,在这种情况下,莫尔斯2-函数是“不确定的”。这是基础性工作的长期目标,定义光滑不变的莫尔斯2-功能使用类似于经典莫尔斯同源性和瑟夫理论的工具。

英文摘要:

We discuss generic smooth maps from smooth manifolds to smooth surfaces, which we call "Morse 2-functions", and homotopies between such maps. The two central issues are to keep the fibers connected, in which case the Morse 2-function is "fiber-connected", and to avoid local extrema over 1-dimensional submanifolds of the range, in which case the Morse 2-function is "indefinite". This is foundational work for the long-range goal of defining smooth invariants from Morse 2-functions using tools analogous to classical Morse homology and Cerf theory.
