It covers the basic background material that an IMO student should be familiar with. These are my “live-TeXed“ notes from the course. Every nonzero ideal of Z has a unique positive generator. High school mathematics, familiarity with proofs by mathematical induction and with the The Euclidean Algorithm and the method of back-substitution 4 4. So Z is a principal ideal domain. Introduction to Number Theory Agata Smoktunowicz 14th January 2020 Lecture 1 Some notes about the course content This year’s Elementary Number Theory A revision by Jim Hefferon, St Michael’s College, 2003-Dec of notes by W. Edwin Clark, University of South Florida, 2002-Dec The formal prerequisites for the material are minimal; in particular no previous course in abstract algebra is required. The present lecture notes contain material for a 5 credit points course in Elemen-tary Number Theory. A Principal Ideal Domain or PID is a (nonzero) commutative ring Rsuch that (i) ab= 0 ()a= 0 or b= 0; (ii) every ideal of Ris principal.
