YMSC Topology Seminar | Braids in planar open books and fillable surgeries

Time：Monday, 16:00-17:00 May 13, 2024

Venue：Room C654 Shuangqing Complex Building ； Zoom meeting ID: 405 416 0815 Password: 111111

Organizer：陈伟彦、高鸿灏、黄意、林剑锋

Speaker：Eylem YILDIZ（Duke University）

Abstract：

We'll give a useful description of braids in #_𝑛(𝑆^1×𝑆^2) using surgery diagrams, which will allow us to address knots in some lens spaces that admit fillable positive contact surgery. We also demonstrate that smooth 16 surgery to the knot 𝑃(-2,3,7) bounds a rational ball, which admits a Stein structure. This answers a question left open by Thomas Mark and Bülent Tosun.
