Hard Diagrams of the Unknot
Benjamin A. Burton, Hsien-Chih Chang, Maarten Löffler +5
We present three "hard" diagrams of the unknot. They require (at least) three extra crossings before they can be simplified to the trivial unknot diagram via Reidemeister moves in…

Parameterized complexity of quantum invariants
Clément Maria
We give a general fixed parameter tractable algorithm to compute quantum invariants of links presented by diagrams, whose complexity is singly exponential in the carving-width (or…

Treewidth, crushing, and hyperbolic volume
Clément Maria, Jessica S. Purcell
We prove that there exists a universal constant such that any closed hyperbolic 3-manifold admits a triangulation of treewidth at most times its volume. The converse is not…
