Introduction to Number Theory Number theory is the study of the integers. In this lecture, we look at a few theorems and The material in the last chapter or two might be considered to be somewhat biased towards analytic number theory, which is hardly surprising since that has been the main thrust of the author’s 3 7 3 7 The disadvantage with this approach is that we have to factor the numbers we get in intermediate stages, which can be very costly if the numbers are large. A PDF book that covers the basics of number theory, such as divisibility, prime numbers, congruences, and cryptography. 2 Making Integers Out of Integers 1 Introduction The main objects of algebraic number theory are number fields.
