MATH41022/MATH31022 - 2011/2012
General Information
Specification
Aims
To show how the tools of Mathematical analysis can be used to prove results about prime numbers and functions defined on the integers.
Brief Course Description
We start by giving two proofs of the infinitude of primes. The methods are elementary but poor in that they do not tell us the truth of how many primes there are. Stronger tools are introduced, improving the results until we can give a proof of the Prime Number Theorem.
Learning Outcomes
On completion of this unit students
- will be able to utilise the correspondence between the product of Dirichlet series and composition of arithmetic functions,
- will be able to use the methods of Partial Summation and replacing sums by integrals,
- be able to prove elementary results on sums over primes,
- be able to prove some analytic properties of the Riemann zeta function,
- appreciate a proof of the Prime Number Theorem,
- will be able to use the Composition Method to estimate sums of arithemtic functions.
