Toroidal and Annular Dehn Fillings

چکیده
Suppose M is a hyperbolic 3-manifold which admits two Dehn fillings M(r1) and M(r2) such that M(r1) contains an essential torus and M(r2) contains an essential annulus. It is known that ∆ = ∆(r1, r2) ≤ 5. We will show that if ∆ = 5 then M is the Whitehead sister link exterior, and if ∆ = 4 then M is the exterior of either the Whitehead link or the 2-bridge link associated to the rational number 3/10. There are infinitely many examples with ∆ = 3.

In this paper we will give three infinite families of examples of nonhyperbolic Dehn fillings on hyperbolic manifolds. A manifold in the first family admits two Dehn fillings of distance two apart, one of which is toroidal and annular, and the other is reducible and ∂-reducible. A manifold in the second family has boundary consisting of two tori, and admits two reducible Dehn fillings. A manifo...
متن کاملOn Hyperbolic 3-manifolds Realizing the Maximal Distance between Toroidal Dehn Fillings
For a hyperbolic 3-manifold M with a torus boundary component, all but finitely many Dehn fillings on the torus component yield hyperbolic 3manifolds. In this paper, we will focus on the situation where M has two exceptional Dehn fillings, both of which yield toroidal manifolds. For such situation, Gordon gave an upper bound for the distance between two slopes of Dehn fillings. In particular, i...
متن کاملToroidal Dehn fillings on hyperbolic 3-manifolds
We determine all hyperbolic 3-manifolds M admitting two toroidal Dehn fillings at distance 4 or 5. We show that if M is a hyperbolic 3manifold with a torus boundary component T0, and r, s are two slopes on T0 with ∆(r, s) = 4 or 5 such that M(r) and M(s) both contain an essential torus, then M is either one of 14 specific manifolds Mi, or obtained from M1, M2, M3 or M14 by attaching a solid tor...
متن کاملDehn Fillings Producing Reducible Manifolds and Toroidal Manifolds
This paper studies one of the problems concerning Dehn fillings producing reducible or toroidal 3-manifolds. Let M be an orientable, irreducible, atoroidal, anannular 3-manifold with T as a torus boundary component. Let γ be an essential simple loop on T . Denote by M(γ) the manifold obtained by Dehn filling along the curve γ, i.e. M(γ) = M ∪φ J , where J is a solid torus, and φ : T ∼= ∂J is a ...

Let M be a simple 3-manifold with a toral boundary component ∂0M . If Dehn filling M along ∂0M one way produces a toroidal manifold and Dehn filling M along ∂0M another way produces a boundary-reducible manifold, then we show that the absolute value of the intersection number on ∂0M of the two filling slopes is at most two. In the special case that the boundary-reducing filling is actually a so...
