Explicit Form of Cassels’ p-adic Embedding Theorem for Number Fields
Published online by Cambridge University Press: 20 November 2018
Abstract
In this paper, we give a general explicit form of Cassels’ $p$-adic embedding theorem for number fields. We also give its refined form in the case of cyclotomic fields. As a byproduct, given an irreducible polynomial $f$ over $\mathbb{Z}$, we give a general unconditional upper bound for the smallest prime number $p$ such that $f$ has a simple root modulo $p$.
