Dirichlet's theorem says that there are infinitely many primes in every arithmetic progression ax+b with coprime a and b. The general proof is analytic, but in certain special cases it is possible to give more elementary, algebraic proofs. The goal of the thesis is to work out in detail the Euclidean proofs approach of [1] and solve related exercises. Besides from learning the basics of algebraic number theory this also requires non-trivial knowledge of Galois theory.
The student may then possibly continue to study the generalization of this approach to arithmetic progressions in other number fields (involving applications of Tchebotarev density theorem).
