# Math Help - Infinitely Many Primes

1. ## Infinitely Many Primes

I've been asked to write an essay on

Some methods for proving that there are infinitely many primes of the form an+b (n=0,1,2,...), when (a,b)=1.

Can anybody help me with a plan of what should be included?

Google for "primes in arithmetic progression". First hit is the Wikipedia article.

3. The proof of this is very involved. It involves a great understanding in analysis and certain functions including the Riemann Zeta function $\zeta(s)$ and Dirichlet L functions; hence one must know a great deal about Dirichlet characters.

A good reference for the full proof can be found in a number theory book by Ireland and Rosen which can be found here.
