"Invariants of knots and links"
We give an overview of some invariants to distinguish knots and links, and discuss some particular algebraic and geometric invariants. We discuss how these invariants relate to the smooth 4-dimensional Poincare conjecture, one of the most important questions in 4-manifold topology.
A post-colloquium meet and greet will be held at 2:00 pm using the same Zoom meeting link.
