Boundary reducible handle additions on simple 3 - manifolds

چکیده
Let M be a simple manifold, and F be a component of ∂M of genus two. For a slope γ on F , we denote by M(γ) the manifold obtained by attaching a 2-handle to M along a regular neighborhood of γ on F . In this paper, we shall prove that there is at most one separating slope γ on F so that M(γ) is ∂-reducible.

Comparing 2-handle Additions to a Genus 2 Boundary Component
A theorem concerning the effects of attaching a 2–handle to a suture on the boundary of a sutured manifold is used to compare the effects of two 2-handle attachments to a genus 2 boundary component of a compact, orientable 3–manifold. We obtain a collection of results relating the euler characteristic of a surface in one of the resulting 3– manifolds to the intersection number of the two curves...
متن کاملHyperbolic Manifolds and Degenerating Handle Additions
A 2-handle addition on the boundary of a hyperbolic 3-manifold M is called degenerating if the resulting manifold is not hyperbolic. There are examples that some manifolds admit infinitely many degenerating handle additions. But most of them are not “basic”. (See section 1 for definitions.) Our first main theorem shows that there are only finitely many basic degenerating handle additions. We al...
متن کاملReducible and ∂-reducible Handle Additions
Let M be a simple 3-manifold with F a component of ∂M of genus at least two. For a slope α on F , we denote by M(α) the manifold obtained by attaching a 2-handle to M along a regular neighborhood of α on F . Suppose that α and β are two separating slopes on F such that M(α) and M(β) are reducible. Then the distance between α and β is at most 2. As a corollary, if g(F ) = 2, then there is at mos...
متن کاملAdding 2–handles to Sutured Manifolds
Combinatorial sutured manifold theory is used to study the effects of attaching a 2–handle to an essential simple closed curve on a genus two boundary component of a compact, orientable 3–manifold. The main results concern degenerating handle additions to a simple 3– manifold and essential surfaces in the exterior of a knot or link obtained by “boring” a split link or unknot. (Boring is an oper...
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 ...
