Heegaard splittings of the pair of solid torus and the core loop.

Chuichiro Hayashi, Koya Shimokawa (2001)

Revista Matemática Complutense

Similarity:

We show that any Heegaard splitting of the pair of the solid torus (≅DxS) and its core loop (an interior point xS) is standard, using the notion of Heegaard splittings of pairs of 3-manifolds and properly imbedded graphs, which is defined in this paper.

Tangle decompositions of satellite knots.

Chuichiro Hayashi, Hiroshi Matsuda, Makoto Ozawa (1999)

Revista Matemática Complutense

Similarity:

We study when an essential tangle decomposition of a satellite knot gives an essential tangle decomposition of the companion knot, that is, when the decomposing sphere can be isotoped to intersect the knotted solid torus identified with the pattern in meridian disks.
