Kronecker's density theorem
Webapply to spaces of holomorphic functions in which the polynomials are dense. 1. Introduction and summary A classical theorem of Kronecker describes the finite-rank Hankel operators or, what is almost the same thing, the finite-rank Hankel forms. In modern language Kronecker's result is for Hankel forms acting on the Hardy space of the unit disk, D. WebWe will prove Theorem 1.1.2 in the next few lectures. Our approach will be to deduce it from a local analogue (see Theorem 1.3.4 ). Theorem 1.1.5. Local Kronecker-Weber. If K / Q p is a finite abelian extension, then K ⊆ Q p ( ζ n) for some , n, where ζ n is a primitive n …

Following an article by Greenberg, published in The Amer-ican Mathematical Monthly in 1974, the presented proof does not use class eld theory, as the most traditional treatments of the theorem do, but rather returns to more basic mathematics, like the original proofs of the theorem [3]. This paper seeks to present
Webˇ. This is similar to the Kronecker-Weber theorem, with sl(!=m) analogous to m= e2ˇi=m. An important case of Kronecker’s work uses the j-function: if Kis imaginary quadratic and we write O K = Z + Z˝ 1, where ˝ 1 is in the upper half-plane, Kronecker showed the number j(˝ 1) is algebraic over Kand its K-conjugates are of the form j(˝ 1 ...

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.
