WebOver Q, the Kronecker-Weber Theorem motiviates the following de nition: De nition . Let L=Q be a nite abelian extension. A positive integer m is called a de ning modulus or an admissible modulus of L if L ˆ Qm. Such an m exists by the Kronecker-Weber theorem. The conductor of L, fL, is the smallest admissible modulus of L. Examples: 1. L = Qm. Webf has a positive (relative) asymptotic density r f. Further-more, r f is a rational number in the interval [(d−1)/d!,1−1/d]. Proof. By the Frobenius Density Theorem the set of primes p for which the fac-torization of f(X)(mod p) contains exactly i linear factors has a Dirichlet density δ i. Therefore, d i=0 δ i = 1.

In fact, once one understands “irrational” merely as “not rational”, then the theorem becomes equivalent to Markov’s principle.
