Mathematics Colloquium, 2007-2008

The mathematics colloquia is a series of talks by the Willamette University Math Department and visiting speakers. These talks are aimed at faculty and undergraduate math students and will introduce the audience to fun, interesting applications of undergraduate mathematics, as well as more advanced topics in mathematics research. Colloquium talks will be held in Collins room 204, on Thursdays at 4:10pm unless stated otherwise. Refreshments will be provided. We hope you can join us! If you would like more information, please contact Prof. Erin McNicholas.

Tangles 

Abstract:

Tangles have served as a building block for mathematicians to study knots, and for biologists to understand DNA recombination. A specific type of tangle, rational tangles, are created by twisting two pieces of string in a specific manner. We will investigate some basic properties of these tangles which will lead us to a simplified proof of Conway's Classification Theorem (1970) by J. R. Goldman and L. H. Kauffman (1997), which states that any two tangles associated with the same rational number are equivalent.
