Title of Seminar: Infosys Chandrasekharan Random Geometry Colloquium
Title of Talk: Alexander polynomial of the mapping torus of a graph map
Speaker: Radhika Gupta, TIFR
Date: November 14, 2022
Time: 16:30:00 Hours
Venue: AG-77
Abstract: Alexander polynomial was originally defined as a tool to differentiate knots. Later, its definition was extended to any finitely presented group. In this talk I will define the polynomial. Then I will explain, with the help of an example, how to obtain a determinant formula for the Alexander polynomial of the fundamental group of the mapping torus of a graph map. Joint with Spencer Dowdall and Sam Taylor.
