Meanings

1. (qualifier:algebraic number theory) A field which includes the rational numbers and has finite dimension as a vector space over the rational numbers.
   • In this section we consider the maximal order of an algebraic number field and discuss the most important consequences which follow from the fact of it being a Dedekind ring. 1989, M. Pohst, H. Zassenhaus, Algorithmic Algebraic Number Theory, 1st paperback edition, Cambridge University Press, published 1997, page 381:

   • Although we shall be concerned in the sequel only with quadratic fields, we shall nevertheless begin with a short discussion of the more general concept of an algebraic number field. 1984, Alan Baker, A Concise Introduction to the Theory of Numbers, Cambridge University Press, page 61:
   • The study of algebraic number fields, and, more generally, of algebraic extensions of the field of rational numbers, is the central topic of algebraic number theory.
