AI总结:

本文通过Heegaard分解方法,为任意接触3流形提供了吉鲁对应关系的证明,扩展了之前针对紧致接触流形的研究。

摘要:

本文利用接触流形的Heegaard分解证明了三维中的吉鲁对应关系。在两位作者之前的论文中,他们通过凸Heegaard表面证明了紧致接触3流形的吉鲁对应关系,同时,Honda、Breen和Huang通过将凸表面理论推广到更高维度,给出了一个适用于所有维度的证明。本文扩展了Heegaard分解方法,以任意(不一定是紧致)接触3流形为目标,以提供一个对低维观众来说可访问的证明。该证明假设了在cobordisms上同胚接触结构的分类移动,这些移动与bypass分解有关;在附录中,我们证明了这一结果在三维情况下的成立。

英文摘要:

This paper proves the Giroux Correspondence in dimension three using Heegaard splittings of contact manifolds. In two of the authors earlier paper they proved the Giroux Correspondence for tight contact 3-manifolds via convex Heegaard surfaces, and simultaneously, Honda, Breen and Huang gave an alldimensions proof of the Giroux Correspondence by generalising convex surface theory to higher dimensions. This paper extends the Heegaard splitting approach to arbitrary (not necessarily tight) contact 3-manifolds in order to provide a proof accessible to a low-dimensional audience. The proof assumes classification moves relating bypass decompositions for isotopic contact structures on cobordisms that are topological products; in the Appendix, we prove this result in the 3- dimensional setting.
