Colloquium - Cameron M. Gordon - The ADE link conjecture


Speaker: Cameron M. Gordon (University of Texas, Austin)

Title: The ADE link conjecture

Abstract: It is well known that the ADE graphs arise in many classification problems in mathematics. In a 2019 paper with Michel Boileau and Steve Boyer we conjectured a modest addition to this list: the fibered links that induce the standard contact structure on S^3 and have a cyclic branched cover whose fundamental group is left-orderable. We will describe the conjecture, its background, and some recent results that establish it in many cases.

This is joint work with Steve Boyer and Ying Hu.
