Notes on constructions of knots with the same trace

Keiji Tagami

The m-trace of a knot is the 4-manifold obtained from B4 by attaching a 2-handle along the knot with m-framing. In 2015, Abe, Jong, Luecke and Osoinach introduc…

A note on stabilization heights of fiber surfaces and the Hopf invariants

Keiji Tagami

In this paper, we focus on the Hopf invariant and give an alternative proof for the unboundedness of stabilization heights of fiber surfaces, which was firstly proved by Baader and…

On annulus presentations, dualizable patterns and RGB-diagrams

Keiji Tagami

The 0-trace of a knot is the 4-manifold represented by the 0-framing of the knot. In this manuscript, we survey methods constructing a pair of knots with diffeomorphic 0-tr…

Knots with infinitely many non-characterizing slopes

Tetsuya Abe, Keiji Tagami

Using the techniques on annulus twists, we observe that 63​ has infinitely many non-characterizing slopes, which affirmatively answers a question by Baker and Motegi. Furthermore…
