3-decompositions of genus two handlebody-knots
Makoto Ozawa, Yi-Sheng Wang
We investigate the class of -decomposable genus two handlebody-knots and provide a complete classification of essential annuli in their exteriors. We introduce the notion of …

Essential annuli in genus two handlebody exteriors
Yuya Koda, Makoto Ozawa, Yi-Sheng Wang
We classify all potential configurations of essential annuli in a genus two atoroidal handlebody exterior in the -sphere, building on two recent classifications: the classificat…
