Flat plumbing basket, self-linking number and Thurston-Bennequin number
Keiji Tagami
A flat plumbing basket is a surface consisting a disk and finitely many bands which are contained in distinct pages of the trivial open book decomposition of . In t…
Flat plumbing basket and contact structure
Tetsuya Ito, Keiji Tagami
A flat plumbing basket is a Seifert surface consisting of a disk and bands contained in distinct pages of the disk open book decomposition of the 3-sphere. In this paper, we examin…
On the Lagrangian fillability of almost positive links
Keiji Tagami
In this paper, we prove that a link which has an almost positive diagram with a certain condition is Lagrangian fillable.
On the maximal degree of the Khovanov homology
Keiji Tagami
It is known that the maximal homological degree of the Khovanov homology of a knot gives a lower bound of the minimal positive crossing number of the knot. In this paper, we show t…
