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

Min Cuts, Shortest Cycles and Planar Graphs, oh my!
A min st-cut is a minimum (weight) set of edges whose removal disconnects the graph, such that the vertex s is in one component and vertex t is in another. Now suppose you want to find many min cuts in the same graph. Can you do this more efficiently than simply computing a min cut for every pair of nodes that you are interested in? It turns out that you can, and we'll see a very elegant solution to this problem, dating to the 60s. We'll also see how, if your input graph is a planar graph, you can find a particular set of min cuts very, very quickly.
