Abstract

top
We give the maximal length of a Newton or a Schinzel sequence in a quadratic extension of a global field. In the case of a number field, the maximal length of a Schinzel sequence is 1, except in seven particular cases, and the Newton sequences are also finite, except for at most finitely many cases, all real. We give the maximal length of these sequences in the special cases. We have similar results in the case of a quadratic extension of a function field 𝔽 q ( T ) , taking in account that the ring of integers may be isomorphic to 𝔽 q [ T ] , in which case there are obviously infinite Newton and Schinzel sequences.
