Link invariants derived from multiplexing of crossings
Waseda University

2:00pm-2:50pm
CMC 108

Abstract

We introduce the multiplexing of a crossing, replacing a classical crossing of a virtual link diagram with multiple crossings which is a mixture of classical and virtual. For integers $$m_{i}$$ ($$i=1,\dotsc,n$$) and an ordered $$n$$-component virtual link diagram $$D$$, a new virtual link diagram $$D(m_{1},\dotsc,m_{n})$$ is obtained from $$D$$ by the multiplexing of all crossings. For welded isotopic virtual link diagrams $$D$$ and $$D'$$, $$D(m_{1},\dotsc,m_{n})$$ and $$D'(m_{1},\dotsc,m_{n})$$ are welded isotopic. From the point of view of classical link theory, it seems very interesting that $$D(m_{1},\dotsc,m_{n})$$ could not be welded isotopic to a classical link diagram even if $$D$$ is a classical one, and new classical link invariants are expected from known welded link invariants via the multiplexing of crossings.

Objects in Maple (and How to Test Them)
Scott Grizzard
2:00pm-2:50pm
CMC 108

Abstract

Maple supports object oriented programming, allowing you to create your own encapsulated, reusuable objects. This talk will introduce object oriented programming, specifically in Maple, using affine transformations as an example. We will also cover the basics of writing scripts to automatically test your objects and procedures to simplify debugging. The final example script is available on github at https://github.com/scottgrizzard/MapleAffineTransformation. Please bring your laptop if you wish to follow and experiment with the code.
