Mike Siddoway Wednesday March 13, 2013 Colorado College "Ideals, Gauss' Lemma, Valuations, Eisenstein's Criterion" Abstract: This talk is roughly about an elementary paper Anh and I have written about all of those things in the title. As this is likely the last mathematics talk I'll give in the coming year, I'll attempt to come as close as possible to talking about absolutely everything. A. N. Whitehead will be mentioned, but I probably won't get to Kierkegaard.
