Abstract

top
The algorithm described in this paper is a practical approach to the problem of giving, for each number field K a polynomial, as canonical as possible, a root of which is a primitive element of the extension K / . Our algorithm uses the L L L algorithm to find a basis of minimal vectors for the lattice of n determined by the integers of K under the canonical map.
