Hi all,

This week's speaker is Anna Parlak from the University of Warwick.

Title: The taut polynomial and the Alexander polynomial Speaker: Anna Parlak, University of Warwick Time: Wednesday, November 11, 2020 - 3:45pm to 4:45pm Room: Virtual meeting https://meet.google.com/yyt-utuu-imr (note that this is a new link)

Abstract: Landry, Minsky and Taylor recently introduced two polynomial invariants of veering triangulations – the taut polynomial and the veering polynomial. I will give the definition of the taut polynomial of a veering triangulation and explain its relationship with the Alexander polynomial of the underlying 3-manifold. I will also discuss how to interpret these results in the case when a veering triangulation carries a fibration over the circle.

Thanks,

Henry
