Concordances to prime hyperbolic virtual knots

Micah Chrisman

Let $Σ_{0}, Σ_{1}$ be closed oriented surfaces. Two oriented knots $K_{0} \subset Σ_{0} \times [0, 1]$ and $K_{1} \subset Σ_{1} \times [0, 1]$ are said to be (virtually) concordant if there is a…

Virtual concordance and the generalized Alexander polynomial

Hans U. Boden, Micah Chrisman

We use the Bar-Natan Zh-correspondence to identify the generalized Alexander polynomial of a virtual knot with the Alexander polynomial of a two component welded link. We show that…
