Alexander polynomials of simple-ribbon knots
Kengo Kishimoto, Tetsuo Shibuya, Tatsuya Tsukamoto +1
In a previous paper, we introduced special types of fusions, so called simple-ribbon fusions on links. A knot obtained from the trivial knot by a finite sequence of simple-ribbon f…
Homotopy, Delta-equivalence and concordance for knots in the complement of a trivial link
Thomas Fleming, Tetsuo Shibuya, Tatsuya Tsukamoto +1
Link-homotopy and self Delta-equivalence are equivalence relations on links. It was shown by J. Milnor (resp. the last author) that Milnor invariants determine whether or not a lin…
Classification of links up to self $#$-move
Tetsuo Shibuya, Akira Yasuhara
A pass-move and a $#$-move are local moves on oriented links defined by L.H. Kauffman and H. Murakami respectively. Two links are self pass-equivalent (resp. self $#$-equivalent) i…
