Abstract
The "Inverse Galois Problem" is a famous unsolved question in algebra, which asks whether or not, given any finite group A, if there is a Galois extension of the rationals whose Galois group is isomophic to A. If such an extension exists, we say "A can be realised as a rational Galois extension". We consider a less general case, presenting a proof that any finite abelian group can be realised as a rational Galois extension. All definitions and results relevant to the proof will be explained (briefly) beforehand.
