Tuesday in Topology seminar, usual time 3:30 central

Hello everyone, Tomorrow in topology seminar we are very happy to have Dan Mathews (Monash University). He will be speaking at 3:30 pm our time. His title and abstract are below along with a NEW zoom link: Title: Symplectic structures in hyperbolic 3-manifold triangulations Abstract: In the 1980s, Neumann and Zagier introduced a symplectic vector space associated to an ideal triangulation of a cusped 3-manifold, such as a knot complement. We give an interpretation for this symplectic structure in terms of the topology of the 3-manifold, via intersections of certain curves on a Heegaard surface. We also give an algorithm to construct curves forming a symplectic basis for this vector space. This approach gives a description of hyperbolic structures on a knot complement via Ptolemy equations, which can be used to calculate the A-polynomial. This talk involves joint work with Jessica Purcell, Joshua Howie and Yi Huang. Neil Hoffman is inviting you to a scheduled Zoom meeting.
