A finiteness theorem for 2-towers of number fields

Xavier Vidaux and Carlos Rodolfo Videla

Abstract:

We show that if a 2-tower (Fn)n0 of number fields does not contain infinitely many Galois quartic extensions, then the structure of the lattice of subfields of the union F of the Fn is completely determined by studying the subfields of F up to some degree.

Keywords: Towers of number fields, 2-towers, lattice of subfields.
