摘要

Let \(n\ge 3\) n 3 and p be an odd prime. We show that for every number field K with \(\zeta _{p} \notin K\) ζ p K , the absolute and tame Galois groups \(\Gamma _K\) Γ K and \(\Gamma ^{ta}_K\) Γ K ta of K satisfy the strong n-fold Massey vanishing property relative to p. Our work is based on an adaptation of the proof of the Scholz–Reichardt theorem.
