A database for number fields

1996
We describe a database for number fields that has been integrated into the algebraic number theory system Kant. The database gives efficient access to the tables of number fields that have been computed during the last years and is easily extended.

The number fields that are O*-fields II

Quaestiones Mathematicae, 2022
An O* -field is a field K for which each partial order with respect to which K is a partially ordered field can be extended to a total order with respect to which K is a totally ordered field. When F is an even finite-dimensional extension field of ℚ contained in ℝ, necessary and sufficient conditions are ...

Definability in number fields

The Journal of Symbolic Logic, 1987
AbstractWe study the sets definable in an algebraic number field by first order formulas of various simple types, showing in particular that N and Z do not have very simple definitions.

Number Fields and Number Rings

1977
A number field is a subfield of ℂ having finite degree (dimension as a vector space) over ℚ. We know (see appendix 2) that every such field has the form ℚ[α] for some algebraic number α ∈ ℂ. If α is a root of an irreducible polynomial over ℚ, having degree n, then $$\mathbb{Q}[\alpha ] = \left\{ {{a_o} + {a_1}\alpha + \cdots + {a_{n - 1}}{\alpha ...
