On the Distribution of Cyclic Number Fields of Prime Degree
Let N Cp (X) denote the number of C p Galois extensions of Q with absolute discriminant ≤ X. A well-known theorem of Wright [1] implies that when p is prime, we have N Cp (X) = c(p)X 1 p−1 + O(X 1 p) for some positive real c(p). In this paper, we improve this result by reducing the secondary error term to O(X
متن کاملThe Lifting of an Exponential Sum to a Cyclic Algebraic Number Field of a Prime Degree
Let E be a cyclic algebraic number eld of a prime degree. We prove an identity which lifts an exponential sum similar to the Kloosterman sum to an exponential sum taken over certain algebraic integers in E.

متن کاملOn divisibility of the class number h+ of the real cyclotomic fields of prime degree l
In this paper, criteria of divisibility of the class number h+ of the real cyclotomic field Q(ζp +ζ−1 p ) of a prime conductor p and of a prime degree l by primes q the order modulo l of which is l−1 2 , are given. A corollary of these criteria is the possibility to make a computational proof that a given q does not divide h+ for any p (conductor) such that both p−1 2 , p−3 4 are primes. Note t...
متن کاملOn the Computation of the Class Number of an Algebraic Number Field
It is shown how the analytic class number formula can be used to produce an algorithm which efficiently computes the class number h of an algebraic number field F. The method assumes the truth of the Generalized Riemann Hypothesis in order to estimate the residue of the Dedekind zeta function of F at s = 1 sufficiently well that h can be determined unambiguously. Given the regulator R of F and ...
