Character prime sums in the Chebotarev proof
ID: character-prime-sums-in-the-chebotarev-proof
The logarithm from the Euler product of an Artin L-function has first-prime-power term . Higher powers are uniformly bounded as real : and . The finitely many ramified local factors also have bounded logarithms. The Artin L-function order at one therefore proves the displayed estimate. Expanding a conjugacy-class indicator by character orthogonality leaves only the trivial character's logarithmic term, with coefficient . This proves Dirichlet density directly; a natural-density assertion needs additional analytic arguments.
