Hello everyone,
Today in topology I will be speaking. My title and abstract are below followed by the zoom link:
Title: Bounds for arithmetic invariants of 3-manifolds Speaker: Neil Hoffman, Oklahoma State University Date: Sep 7, 2021 Time: 3:00 PM Room: Virtual meeting Abstract: A hyperbolic 3-manifold is the quotient of $H^3$ by $\Gamma$ a discrete subgroup of $PSL(2, C)$. In fact, this subgroup $\Gamma$ carries a substantial amount of arithmetic information. I will discuss some of the background for defining a hyperbolic 3-manifold this way and show how this leads to upper bounds on the degrees of fields used define this data. Finally, I will describe how this perspective fits into joint work with K. Petersen.
Neil Hoffman is inviting you to a scheduled Zoom meeting.
