Random Galois extensions of Hilbertian fields
Journal de théorie des nombres de Bordeaux, Tome 25 (2013) no. 1, pp. 31-42.

Soit L une extension galoisienne d’un corps K hilbertien et dénombrable. Bien que L ne soit pas nécessairement hilbertien, nous montrons qu’il existe beaucoup de grandes sous-extensions de L/K qui le sont.

Let L be a Galois extension of a countable Hilbertian field K. Although L need not be Hilbertian, we prove that an abundance of large Galois subextensions of L/K are.
