Seifert Klein bottles for knots with common boundary slopes

We consider the question of how many essential Seifert Klein bottles with common boundary slope a knot in S^3 can bound, up to ambient isotopy. We prove that any hyperbolic knot in S^3 bounds at most six Seifert Klein bottles with a given boundary slope. The Seifert Klein bottles in a minimal projection of hyperbolic pretzel knots of length 3 are shown to be unique and pi_1-injective, with surgery along their boundary slope producing irreducible toroidal manifolds. The cable knots which bound… 

Examples of hyperbolic knots with distance 3 toroidal surgeries in the 3-sphere

A classification of hyperbolic knots in S admitting two toroidal surgeries at distance 3, whose slopes are represented by twice punctured essential separating tori, whose knots belong to a family K(a, b, n), where a,b, n are integers and gcd( a, b) = 1.

Correction to "Toroidal and Klein bottle boundary slopes"

Let M be a compact, connected, orientable, irreducible 3-manifold and T an incompressible torus boundary component of M such that the pair (M,T) is not cabled. In the paper "Toroidal and Klein bottle

Homeomorphisms between pairs of genus two handlebodies and separating circles in their boundaries

A known result in low-dimensional topology is that every incompressible surface properly embedded in a genus two handlebody is boundary compressible. This result produces a pair consisting of a genus

Seifert surfaces for genus one hyperbolic knots in the 3–sphere

We prove that any collection of mutually disjoint and non-parallel genus one orientable Seifert surfaces in the exterior of a hyperbolic knot in the 3sphere has at most 5 components and that this



Complements of Minimal Spanning Surfaces of Knots are Not Unique

Every polyhedral simple closed curve in S3 bounds an orientable surface [2]; that is, if k is a knot, then there exists an orientable surface S such that D(S) = k. The minimal genus of all such

Dehn surgeries on knots creating essential tori, II

In this paper, which is a sequel to [GLul], we continue our study of when Dehn surgery on a hyperbolic knot K in S can yield a manifold that contains an incompressible torus. Let E(K) denote the

Dehn surgery on knots

In [D], Dehn considered the following method for constructing 3-manifolds: remove a solid torus neighborhood N(K) of some knot X in the 3-sphere S and sew it back differently, showing that one could obtain infinitely many non-simply-connected homology spheres o in this way.

Incompressible spanning surfaces and maximal fibred submanifolds for a knot

In a previous paper [7] we introduced and studied maximal fibred submanifolds of the exterior of a knot. In this paper we shall investigate the relation of these submanifolds to the number of

Crosscap number two knots in $S^3$ with (1,1) decompositions

M. Scharlemann has recently proved that any genus one tunnel number one knot is either a satellite or 2-bridge knot, as conjectured by H. Goda and M. Teragaito; all such knots admit a (1,1)

Knots with infinitely many minimal spanning surfaces

Introduction. If K is a polygonal representative of a tame knot in S3, then K is spahned by a polyhedral, orientable surface [10, ?7], [23]; an orientable spanning surface of smallest possible genus

Foliations and the topology of 3-manifolds

In this announcement we discuss the close relationship between the topology of 3-manifolds and the foliations that is possesses. We will introduce and state the main result, then use it and the ideas
