1 F eb 1 99 7 REAL FIELDS AND REPEATED RADICAL EXTENSIONS
1. Introduction. Recall that a field extension F ⊆ L is said to be a radical extension if it is possible to write L = F [α], where α ∈ L is an element with α n ∈ F for some positive integer n. More generally, an extension F ⊆ L is a repeated radical extension if there exist intermediate fields L i with F = L 0 ⊆ L 1 ⊆ · · · ⊆ L r = L and such that each field L i is a radical extension of L i−1 ...
متن کاملZp-Extensions of Totally Real Fields
We continue our investigations into complex and p-adic variants of H. M. Stark’s conjectures [St] for an abelian extension of number fields K/k. We have formulated versions of these conjectures at s = 1 using so-called ‘twisted zeta-functions’ (attached to additive characters) to replace the more usual L-functions. The complex version of the conjecture was given in [So3]. In [So4] we formulated...
متن کاملQuadratic extensions of totally real quintic fields
In this work, we establish lists for each signature of tenth degree number fields containing a totally real quintic subfield and of discriminant less than 1013 in absolute value. For each field in the list we give its discriminant, the discriminant of its subfield, a relative polynomial generating the field over one of its subfields, the corresponding polynomial over Q, and the Galois group of ...
متن کاملRadical Extensions and Crossed Characters
E. Witt has given a theory of abelian extensions of fields containing sufficiently many roots of unity which consists essentially, as has been remarked before, in applying the theory of characters of finite abelian groups. There exists now a sufficiently developed theory of crossed characters, and it is the object of this note to show that a fairly complete and simple theory of radical extensio...
متن کاملRadical Extensions of Rings
Jacobson's generalization [5, Theorem 8] of Wedderburn's theorem [8] states that an algebraic division algebra over a finite field is commutative. These algebras have the property that some power2 of each element lies in the center. Kaplansky observed in [7] that any division ring, or, more generally, any semisimple ring, in which some power of each element lies in the center is commutative. Ka...
