We show that if a knot admits a prime, twist-reduced diagram with at least 4 twist regions and at least 6 crossings per twist region, then every non-trivial Dehn filling of that knot is …

A horospherical torus about a cusp of a hyperbolic manifold inherits a Euclidean similarity structure, called a cusp shape. We bound the change in cusp shape when the hyperbolic …
We show that the cusp volume of a hyperbolic alternating knot can be bounded above and below in terms of the twist number of an alternating diagram of the knot. This leads to …
We survey some tools and techniques for determining geometric properties of a link complement from a link diagram. In particular, we survey the tools used to estimate …
Developed from geometric arguments for bounding the MorseNovikov number of a link in terms of its tunnel number, we obtain upper and lower bounds on the handle number of a …

We find that cusp densities of hyperbolic knots in $ S^ 3$ include a dense subset of $[0, 0.6826\dots] $ and those of links are a dense subset of $[0, 0.853\dots] $. We define a new …

We show that the set of cusp shapes of hyperbolic tunnel number one manifolds is dense in the Teichmüller space of the torus. A similar result holds for tunnel number $ n $ manifolds …
For every knot or link with hyperbolic complement, each cusp of the complement has a geometric shape given by the Euclidean similarity class of structures on horoball …
Sean K un nudo en S3 y N= K× D2 una vecindad regular de K. Tomemos µ={x}×∂ D2, λ= K×{y}(y∈∂ D2), un meridiano y una longitud del toro T= K×∂ D2, respectivamente. Una …
