摘要:

我们提出了在$3$维流形上重构具有指定原像的Morse-Bott函数的条件。本研究加强了作者先前关于Morse函数情形的结果,并给出了一个相关示例作为另一项结果。这展示了关于重构良好光滑函数使得原像符合指定要求的新结果。此类研究是基础且自然的,但令人惊讶的是,它直到2006年才由Sharko创立。例如,闭曲面上良好光滑函数的重构随后由Masumoto-Saeki跟进,后来Gelbukh、Marzantowicz、Michalak等人进一步研究了Morse函数的情形。作者已开始针对$3$维情形进行显式研究,尊重单点原像的拓扑,并获得了若干结果。我们在此补充另一项相关结果。

英文摘要:

We present conditions for reconstruction of Morse-Bott functions with prescribed preimages on $3$-dimensional manifolds. The present work strengthens a previous result for the Morse function case by the author and present a related example as another result. This shows a new result on reconstruction of nice smooth functions such that preimages are as prescribed. Such a study has been fundamental, natural, and surprisingly, founded recently, in 2006, by Sharko. Reconstruction of nice smooth functions on closed surfaces has been followed by Masumoto-Saeki, for example, and later, Gelbukh, Marzantowicz, Michalak, and so on, are studying Morse function cases further. The author has started explicit studies for $3$-dimensional cases respecting topologies of preimages of single points and obtained several results. We add another result on this.
