The Greater Topology seminar is a hybrid seminar which contains both online talks and in-person talks. It intends to be held on biweekly Wednesday evening, 8-9 pm DC time this semester. In the seminar, we will explore covers of link complements in both algebraic and geomeotric ways. We welcome speakers who are intersted in connections between covers and link invariants. We use zoom.
