Abstract

Let p be a prime number and F a field containing a root of unity of order p. We relate recent results on vanishing of triple Massey products in the mod-p Galois cohomology of F, due to Hopkins, Wickelgren, Mináč and Tân, to classical results in the theory of central simple algebras. We prove a stronger form of the vanishing property for global fields.
