Description: An asynchronous seminar on knot theory at External HomePage

We built this site to serve as an asynchronous seminar on knot theory. The first posts will be taken from talks scheduled for the (now cancelled) AMS Spring Sectional Meetings. New posts will usually appear Monday mornings. If you would like your talk to appear here, please upload it to youtube and we will embed it as a blog post. Viewers will post questions to your talk and you may answer (or not) at your leisure!

Talks are available at

We particularly welcome talks on virtual knots, welded knots, quandles, racks, non-associative algebra, combinatorial knot theory, and applications of knot theory. We will gladly post presentations on knot theory or any related topic.
