A Fast, Strong, Topologically Meaningful and Fun Knot Invariant
Dror Bar-Natan, Roland van der Veen
In this paper we discuss a pair of polynomial knot invariants which is: * Theoretically and practically fast: can be computed in polynomial time. We can compute i…
A plumbing-multiplicative function from the Links-Gould invariant
Daniel Lopez-Neumann, Roland van der Veen
We prove that the Laurent polynomial in that is the top coefficient of the Links-Gould invariant of the boundary of a Seifert surface is multiplicative unde…
A perturbed Alexander polynomial for singular knots
Martine Schut, Roland van der Veen
We introduce a version of the Alexander polynomial for singular knots and tangles and show how it can be strengthened considerably by introducing a perturbation. For singular long…
Non-semisimple quantum invariants of fibred links
Daniel López Neumann, Roland van der Veen
The Akutsu-Deguchi-Ohtsuki (ADO) invariants are the most studied quantum link invariants coming from a non-semisimple tensor category. We show that, for fibered links in , the…
