Virtual Seifert Surfaces
Micah Chrisman
A virtual knot that has a homologically trivial representative in a thickened surface is said to be an almost classical (AC) knot. then…
Signature and concordance of virtual knots
Hans U. Boden, Micah Chrisman, Robin Gaudreau
We introduce Tristram-Levine signatures of virtual knots and use them to investigate virtual knot concordance. The signatures are defined first for almost classical knots, which ar…
Virtual knot cobordism and bounding the slice genus
Hans U. Boden, Micah Chrisman, Robin Gaudreau
In this paper, we compute the slice genus for many low-crossing virtual knots. For instance, we show that 1295 out of 92800 virtual knots with 6 or fewer crossings are slice, and t…
Relating virtual knot invariants to links in
Micah Chrisman, Robert G. Todd
Geometric interpretations of some virtual knot invariants are given in terms of invariants of links in . Alexander polynomials of almost classical knots are shown to…
