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… Expand

We introduce a new technique for finding CAT(-1) surfaces in hyperbolic 3-manifolds. We use this to show that a complete hyperbolic 3-manifold with finitely generated fundamental group is… Expand

A group of homeomorphisms of the circle satisfying the "convergence property" is shown to be the restriction of a discrete group of Mobius transformations of the unit disk. This completes the proof… Expand

It is a well-established principle in manifold topology that by studying codimension-1 objects and their complementary pieces one obtains a great deal of topological and geometric information about… Expand

IN THIS paper we investigate the topology of manifolds obtained by nontrivial surgery on a knot k in D2 x S’. In particular this work together with the work of Berge [l] yields a complete solution to… Expand

New piperidine derivatives and in particular esters and amides of substituted (piperidinyl-4) acetic acid are used as stabilisers for polymers, especially for polyolefines.

IN THIS paper we define a simple geometric operation, disc decomposition, which when successfully applied to a surface R in S3 implies that R is a surface of minimal genus for the oriented link L =… Expand

This paper introduces a rigorous computer-assisted procedure for analyzing hyperbolic 3-manifolds. This procedure is used to complete the proof of several long-standing rigidity conjectures in… Expand
