On the Group Structure of "Magic" Leatherworking Braids
William Hobkirk, Abigail Hollingsworth, Elisabetta A. Matsumoto +1
\emph{Magic braids} are used in leatherworking to make intricate straps and bands. They appear to be impossible to make. To determine which braids can be made with this leatherwork…
A robot that unknots knots
Connie On Yu Hui, Dionne Ibarra, Louis H. Kauffman +4
Consider a robot that remembers only the starting position and walks along a knot once on a knot diagram, switching every undercrossing it meets until it returns to the starting po…
Links on incompressible surfaces and volumes
Corbin Reid
We consider volumes of two families of links that have been the focus of recent results on geometry, namely weakly generalised alternating (WGA) links and fully augmented links (FA…
Geometry of fully augmented links in doubled 3-manifolds
Jessica S. Purcell, Corbin Reid, John Stewart
Classical fully augmented links have explicit hyperbolic geometry, and have diagrams on the 2-sphere in the 3-sphere. We generalise to construct fully augmented links projected to…
