講演題目 A necessary condition for constituent knots of reducible genus two handlebody-knots
アブストラクト A knot K is a constituent knot of a genus two handlebody-knot H if there is a non-separating disk D in H such that the core of cl(H-N(D)) is K.
We characterize constituent knots of a non-trivial reducible genus two handlebody-knot in terms of an incompressible torus (or two incompressible tori) in the exterior of the handlebody-knot.
