A coherent band surgery is a local move of an oriented knot or link by doing a surgery along an added band. The coherent band-Gordian distance between two links is the minimum number of coherent band surgeries needed to transform one into the othe...

COMMUNICATIONS OF THE KOREAN MATHEMATICAL SOCIETY   33(2) 591-604   2018   [Refereed]
We consider a family of ribbon 2-knots with trivial Alexan- der polynomial. We give nonabelian SL(2,C)-representations from the groups of these knots, and then calculate the twisted Alexander polyno- mials associated to these representations, whic...

JOURNAL OF KNOT THEORY AND ITS RAMIFICATIONS   26(8)    Jul 2017   [Refereed]
We enumerate ribbon 2-knots presented by virtual arc diagrams with up to four classical crossings. We use a linear Gauss diagram for a virtual arc diagram.

Twisted Alexander polynomial of a ribbon 2-knot [Invited]
Taizo Kanenobu
The 14th East Asian Conference on Geometric Topology   22 Jan 2019   
The twisted Alexander polynomial is a rational function, not necessarily a polynomial. It is shown that for a ribbon 2-knot, the twisted Alexander polynomial associated to an irreducible representation of the knot group to SL(2; F) is always a pol...

The 10th KOOK-TAPU Joint Seminar on Knots and Related Topics   26 Jul 2018   
In general, the twisted Alexander polynomial is a rational function, not necessarily a polynomial. It is shown that for a ribbon 2-knot of 1-fusion, the twisted Alexander polynomial associated to a irreducible representation of the knot group to S...

We consider a family of ribbon 2-knots with trivial Alexander polynomial. We give nonabelian Tex-representations from the groups of these knots, and then calculate the twisted Alexander polynomials associated to these representations, which ...
