On computing subfields. A detailed description of the algorithm

Journal de théorie des nombres de Bordeaux

Similarity:

Let ( α ) be an algebraic number field given by the minimal polynomial f of α . We want to determine all subfields ( β ) ( α ) of given degree. It is convenient to describe each subfield by a pair ( g , h ) [ t ] × [ t ] such that g is the minimal polynomial of β = h ( α ) . There is a bijection between the block systems of the Galois group of f and the subfields of ( α ) . These block systems are computed using cyclic subgroups of the Galois group which we get from the Dedekind criterion. When a block system is known we compute the corresponding...

An alternative construction of normal numbers

Edgardo Ugalde (2000)

Journal de théorie des nombres de Bordeaux

Similarity:

A new class of b -adic normal numbers is built recursively by using Eulerian paths in a sequence of de Bruijn digraphs. In this recursion, a path is constructed as an extension of the previous one, in such way that the b -adic block determined by the path contains the maximal number of different b -adic subblocks of consecutive lengths in the most compact arrangement. Any source of redundancy is avoided at every step. Our recursive construction is an alternative to the several well-known...
