Dirichlet series associated to quartic fields with given cubic resolvent

چکیده
Let k be a cubic field. We give an explicit formula for the Dirichlet series ∑ K |Disc(K)|−s, where the sum is over isomorphism classes of all quartic fields whose cubic resolvent field is isomorphic to k. Our work is a sequel to the unpublished preprint [12] whose results have been summarized in [7], so we include complete proofs so as not to rely on unpublished work. This is a companion paper to [14] where we compute the Dirichlet series associated to cubic fields having a given quadratic resolvent.

Dirichlet Series Associated to Quartic Fields with given Resolvent
Let k be a cubic field. We give an explicit formula for the Dirichlet series P K |Disc(K)| −s, where the sum is over isomorphism classes of all quartic fields whose cubic resolvent field is isomorphic to k. Our work is a sequel to the unpublished preprint [11] whose results have been summarized in [6], so we include complete proofs so as not to rely on unpublished work. This is a companion pape...
متن کاملAppendix To: Dirichlet Series Associated to Quartic Fields with given Resolvent
This is an appendix to our paper [1], where we give an explicit formula for the Dirichlet series ∑ K |Disc(K)|−s, where the sum is over isomorphism classes of all quartic fields whose cubic resolvent field is isomorphic to k. In the present note, we give a complete proof of a theorem enumerating splitting types of certain number fields, which was stated in [1] without a complete proof. The deta...
متن کاملError Estimates for the Davenport–heilbronn Theorems
We obtain the first known power-saving remainder terms for the theorems of Davenport and Heilbronn on the density of discriminants of cubic fields and the mean number of 3-torsion elements in the class groups of quadratic fields. In addition, we prove analogous error terms for the density of discriminants of quartic fields and the mean number of 2-torsion elements in the class groups of cubic f...
متن کاملOn the Field Intersection Problem of Quartic Generic Polynomials via Formal Tschirnhausen Transformation
Let k be a field of characteristic 6= 2. We give an answer to the field intersection problem of quartic generic polynomials over k via formal Tschirnhausen transformation and multi-resolvent polynomials.
متن کاملModuli Spaces for Rings and Ideals
The association of algebraic objects to forms has had many important applications in number theory. Gauss, over two centuries ago, studied quadratic rings and ideals associated to binary quadratic forms, and found that ideal classes of quadratic rings are exactly parametrized by equivalence classes of integral binary quadratic forms. Delone and Faddeev, in 1940, showed that cubic rings are para...
