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…

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…
