MATH31022 - 2008/2009

 

Specification

Aims

To prove some basic results in number theory.

Brief Course Description

The distribution of the prime numbers appears to be rather irregular, although they certainly thin out as x increases. How can we describe the distribution? How many primes are there less than x? The key to all this is the Riemann Zeta function, the Riemann zeros, and the famous Explicit Formulas in Number Theory. The Riemann Formula counts up precisely the number of primes less than x. This formula contains oscillatory terms corresponding to the Riemann zeros, and gives rise to the "music of the primes".

Learning Outcomes

On successful completion of this course students will:

• Work with the Riemann zeta function.
• have some familiarity with the Explicit Formulas of number theory.
