Link invariants from finite Coxeter racks

Sam Nelson, Ryan Wieghard

We study Coxeter racks over and the knot and link invariants they define. We exploit the module structure of these racks to enhance the rack counting invariants and…

Virtual Yang-Baxter cocycle invariants

Jose Ceniceros, Sam Nelson

We extend the Yang-Baxter cocycle invariants for virtual knots by augmenting Yang-Baxter 2-cocycles with cocycles from a cohomology theory associated to a virtual biquandle structu…
