Quandles and Linking Number
Natasha Harrell, Sam Nelson
We study the quandle counting invariant for a certain family of finite quandles with trivial orbit subquandles. We show how these invariants determine the linking number of classic…

Non-classicality and quandle difference invariants
Natasha Harrell, Sam Nelson
Non-classical virtual knots may have non-isomorphic upper and lower quandles. We exploit this property to define the quandle difference invariant, which can detect non-classicality…
