Trisections induced by the Gluck surgery along certain spun knots

Tsukasa Isoshima, Masaki Ogawa

Gay and Meier asked whether or not a trisection diagram obtained by the Gluck twist on a spun or a twist spun 2-knot obtained from some method is standard. In this paper, we depict…

Some lower bounds for the Kirby-Thompson invariant

Nobutaka Asano, Hironobu Naoe, Masaki Ogawa

Kirby and Thompson introduced a non-negative integer-valued invariant, called the Kirby-Thompson invariant, of a -manifold using trisections. In this paper, we give some lower b…

Stable equivalence of handlebody decompositions whose partitions are multibranched surfaces

Masaki Ogawa

In this paper, we consider decompositions of closed orientable 3-manifolds with more than 3 handlebodies, where the union of intersections of handlebodies is a multibranched surfac…

Handlebody decompositions of 3-manifolds and polycontinuous patterns

Naoki Sakata, Ryosuke Mishina, Masaki Ogawa +4

We introduce the concept of a handlebody decomposition of a 3-manifold, a generalization of a Heegaard splitting, or a trisection. We show that two handlebody decompositions of a c…

Trisections with Kirby-Thompson length 2

Masaki Ogawa

Kirby and Thompson introduced a length of a trisection. They also defined the length of a 4-manifold as the minimum of length among all lengths of trisection of a 4-manifold. In th…

Decompositions of the 3-sphere and lens spaces with three handlebodies

Yasuyoshi Ito, Masaki Ogawa

In this paper, we consider decompositions of 3-manifolds with three handlebodies. We classify such decompositions of the 3-sphere and lens spaces with small genera. These decomposi…
