YMSC Topology Seminar | An L^2-version of Alexander polynomial and 3-dimensional topology

Time：Monday, 16:00-17:00 April 29, 2024

Venue：C654 Shuangqing Complex Building Online： Zoom meeting ID: 405 416 0815 Pw: 111111

Organizer：陈伟彦、高鸿灏、黄意、林剑锋

Speaker：Jiaru Duan 段剑儒 (Peking University)

Abstract：

The L^2-Alexander torsion is an invariant associated to a 3-manifold and an 1-cohomology class. This invariant is a real function with many properties similar to / generalizing the tranditional Alexander polynomial. In this talk, I will discuss the "leading coefficient" of this function and show its connection with sutured manifold theory.
