Mathematics Colloquium

Calendar of upcoming talks available here

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. Unless otherwise noted, Colloquium talks will be held Thursdays at 4:00pm in Ford Room 102. Refreshments will be provided. We hope you can join us! If you would like more information, please contact Prof. Erin McNicholas.

Colloquium Schedule 2013-2014

Thursday, April 10th, Ford Hall 102 at 4:00pm 

Gary Gordon, Lafayette College

Pick a Tree, Any Tree

Trees are an extremely important and useful topic in graph theory and network design. I'll talk about some of the motivation and history of the subject, including Cayley's famous formula that counts the number of spanning trees of a complete graph. Then we'll use that formula to figure out the probability that a randomly chosen subtree of a complete graph is a spanning tree. This is joint work with Alex Chin, Kelly MacPhee and Charles Vincent, three undergraduates in Lafayette College's REU program last summer. No prior knowledge of graph theory will be assumed.
