关于切触结构的支撑亏格

On the support genus of a contact structure

Mehmet Firat Arikan

摘要:

Akbulut-Ozbagci给出的算法构造了一个由三球面上的一个环节上的切触手术描述的切触三流形上的显式开卷分解。本文将利用Giroux的接触胞腔剖分过程对该算法进行改进。我们的算法是更经济的选择支持亏格的开放的书,特别是它给了一个很好的上界最近定义的“最小支持亏格不变量”的切触结构。

英文摘要:

The algorithm given by Akbulut-Ozbagci constructs an explicit open book decomposition on a contact three-manifold described by a contact surgery on a link in the three-sphere. In this article, we will improve this algorithm by using Giroux's contact cell decomposition process. Our algorithm is more economical on choosing the supporting genus of the open book; in particular it gives a good upper bound for the recently defined ``minimal supporting genus invariant'' of contact structures.
