0 Preface This set of notes on number theory was originally written in 1995 for students at the IMO level. The Euclidean Algorithm and the method of back-substitution 4 4. In nite continued fractions 19 10. 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 present lecture notes contain material for a 5 credit points course in Elemen-tary Number Theory. Conventions are as follows: Each lecture gets its own “chapter,” and appears in the table of contents with the date. Basic Number Theory 1 1. Chapter 1. The natural numbers 1 2. The integers 3 3. This text is meant to be a reference, and Every nonzero ideal of Z has a unique positive generator. The tabular method 7 5. 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. The notes contain a useful introduction to important topics that need to be ad-dressed in a course in number theory. The formal prerequisites for the material are minimal; in particular no previous course in abstract algebra is required. Online Math Courses, videos and lectures from leading universities.This has links to some excellent number theory courses. These notes serve as course notes for an undergraduate course in number the-ory. It covers the basic background material that an IMO student should be familiar with. Finite continued fractions 17 9. MA257: INTRODUCTION TO NUMBER THEORY LECTURE NOTES 2018 5 De nition 1.1.5. The theorems of Fermat and Euler. Notes of Number Theory by Umer Asghar These notes are very helpful to prepare one of the sections paper of mathematics for BSc. These are my “live-TeXed“ notes from the course.
