Links with no exceptional surgeries

D Futer, JS Purcell - Commentarii Mathematici Helvetici, 2007 - ems.press
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 …

[PDF][PDF] Cusp shapes under cone deformation

JS Purcell - Journal of Differential Geometry, 2008 - projecteuclid.org
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 …

Cusp volumes of alternating knots

M Lackenby, J Purcell - Geometry & Topology, 2016 - msp.org
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 …

A survey of hyperbolic knot theory

D Futer, E Kalfagianni, JS Purcell - International Conference on KNOTS, 2016 - Springer
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 …

Morse-Novikov numbers, tunnel numbers, and handle numbers of sutured manifolds

KL Baker, F Manjarrez-Gutiérrez - Journal of Differential Geometry, 2025 - projecteuclid.org
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 …

Densities of hyperbolic cusp invariants of knots and links

C Adams, R Kaplan-Kelly, M Moore, B Shapiro… - Proceedings of the …, 2018 - ams.org
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 …

Cusp shape and tunnel number

V Dang, J Purcell - Proceedings of the American Mathematical Society, 2019 - ams.org
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 …

[图书][B] Cusp shapes of hyperbolic link complements and Dehn filling

JS Purcell - 2004 - search.proquest.com
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 …
