Number Theory Seminar: Wednesdays, 4:15-5:45 Speakers are invited to consider the first half hour of the talk as general background on their field of interest. The seminar takes a short break after one hour so that participants who have later commitments can leave if necessary. The third half-hour can be reserved for technical details aimed at specialists. The seminar was founded in 1972 by Carl Pomerance, Mary Dauenhaur and John Hunsucker, the year Dauenhaur and Pomerance were hired at UGA. The participants read Tate's unpublished lecture notes "Rational points on elliptic curves'', Philips Lectures, Haverford College, Haverford, Pa., 1961. This led Penney and Pomerance to search and find elliptic curves of rank at least 6 and at least 7 over the rationals, record ranks at the time. 50 PhD Graduates and their Dissertations 2023 Tyler Genao (Pete Clark), Freddy Saia (Pete Clark), 2022 Komal Agrawal (Paul Pollack), On Some Problems Concerning Integer Recurring Sequences.
