The Massey vanishing conjecture for number fields

Number Theory 2023-02-01 v2 Algebraic Geometry

Abstract

A conjecture of Min\'a\v{c} and T\^an predicts that for any n>2, any prime p and any field k, the Massey product of n Galois cohomology classes in H^1(k,Z/pZ) must vanish if it is defined. We establish this conjecture when k is a number field.
