Seifert surfaces in open books, and a new coding algorithm for links

Rei Furihata, Mikami Hirasawa, Tsuyoshi Kobayashi

We introduce a new standard form of a Seifert surface $F$ . In that standard form, $F$ is obtained by successively plumbing flat annuli to a disk $D$ , where the gluing regions are a…

Heegaard genus of the connected sum of m-small knots

Tsuyoshi Kobayashi, Yo'av Rieck

We prove that if $K_{1} \subset M_{1}, ..., K_{n} \subset M_{n}$ are m-small knots in closed orientable 3-manifolds then the Heegaard genus of $E(#_{i=1}^n K_i)$ is strictly less than the su…
