Vassiliev invariants as polynomials

Simon Willerton (1998)

Banach Center Publications

Similarity:

Three results are shown which demonstrate how Vassiliev invariants behave like polynomials.

Homfly polynomials as vassiliev link invariants

Taizo Kanenobu, Yasuyuki Miyazawa (1998)

Banach Center Publications

Similarity:

We prove that the number of linearly independent Vassiliev invariants for an r-component link of order n, which derived from the HOMFLY polynomial, is greater than or equal to min{n,[(n+r-1)/2]}.

On numerical invariants for knots in the solid torus

Khaled Bataineh (2015)

Open Mathematics

Similarity:

We define some new numerical invariants for knots with zero winding number in the solid torus. These invariants explore some geometric features of knots embedded in the solid torus. We characterize these invariants and interpret them on the level of the knot projection. We also find some relations among some of these invariants. Moreover, we give lower bounds for some of these invariants using Vassiliev invariants of type one. We connect our invariants to the bridge number in the solid...
