Biquandles of Virtual Knots

I haven’t quite gotten to the notion of a quandle yet, but it’s just around the corner. Still, if you’re interested in knot theory, there’s a paper just up on the arXiv by David Hrencecin and his former advisor Louis Kauffman (who I’ll be seeing again in Ohio next weekend). It’s on an invariant of virtual knots, which is another thing that I should talk about.
