Abstract:We construct infinite Galois extensions $ L$ of $ \mathbb{Q}$ that satisfy the Northcott property on elements of small height, and where this property can be deduced solely from the local behavior of $ L$ at the different prime numbers. We also give examples of Galois extensions of $ \mathbb{Q}$ which have finite local degree at all prime numbers and do not satisfy the Northcott property.
