Title: My favorite numberSpeaker: John Baez Affiliation: University of California, Riverside Room: DC 1302
Abstract: The number 24 plays a central role in mathematics thanks to a series of "coincidences" that is just beginning to be understood. One of the first hints of this fact was Euler's bizarre "proof" that
1\^ + 2\^ + 3\^ + 4\^ + … = -1/12\^
Title: The Replication ConjectureSpeaker: Ahmad Abdi Affiliation: University of Waterloo Room: MC 5417
Abstract: In 1972, Lovasz proved a key lemma that was the piece of the puzzle Fulkerson missed to prove the weak perfect graph theorem. This important lemma, called the Duplication Lemma, simply states that vertex duplication preserves graph perfection.

Title: Presenting a tangleSpeaker: Jim Geelen Affiliation: University of Waterloo Room: MC 5417
Abstract: A tangle of order $k$ in a matroid is an abstract notion that describes a “$k$-connected component” of a matroid. Tangles are very useful in theoretical applications, but in practice they suffer from being difficult to describe succinctly. In this talk we try to address that issue and present some negative result
