T his semester\, I will present a subject which is also central in number an d has numerous applications (not only to number theory!): modular forms. T o illustrate the theory\, textbook authors often use modular forms find id entities involving the sum-of-divisors functions\, but this is soooo borin g! Instead\, I will present a powerful\, beautiful and (relatively) modern proof of Lagrange's four square theorem\, which answers the following sim ple question: which integers are a sum of four squares? Can you guess the answer? \n\n \n\nSee you all there!\n\n \n\nAll graduate students are invi ted. As with all talks in the graduate student seminar\, this talk will be accessible to all graduate students in math and stats. This seminar was m ade possible by funding from the 91ºÚÁÏÍø mathematics and statistics departm ent\, PGSS\, and GSAMS.\n DTSTART:20170203T180000Z DTEND:20170203T180000Z LOCATION:BURN 1025 (10th Floor) - Graduate Lounge\, Burnside Hall\, CA\, QC \, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:MATHSTAT GRAD STUDENT SEMINAR URL:/mathstat/channels/event/mathstat-grad-student-sem inar-265544 END:VEVENT END:VCALENDAR
