Tchebotarev density theorem (Theorem)

Let $ L/K$ be any finite Galois extension of number fields with Galois group $ G$. For any conjugacy class $ C \subset G$, the subset of prime ideals $ \mathfrak{p} \subset K$ which are unramified in $ L$ and satisfy the property

$\displaystyle [L/K,\mathfrak{P}] \in C\ $   for any prime $\displaystyle \ \mathfrak{P} \subset L\ $   containing $\displaystyle \ \mathfrak{p} $
has analytic density $ \frac{\vert C\vert}{\vert G\vert}$, where $ [L/K,\mathfrak{P}]$ denotes the Artin symbol at $ \mathfrak{P}$.

Note that the conjugacy class of $ [L/K,\mathfrak{P}]$ is independent of the choice of prime $ \mathfrak{P}$ lying over $ \mathfrak{p}$, since any two such choices of primes are related by a Galois automorphism and their corresponding Artin symbols are conjugate by this same automorphism.
