The strong Massey vanishing conjecture for fields with virtual cohomological dimension at most $1$

Algebraic Geometry 2022-07-05 v7

Abstract

We show that a strong vanishing conjecture for nn-fold Massey products holds for fields of virtual cohomological dimension at most 11 using a theorem of Haran. We also prove the same for PpC fields, using results of Haran--Jarden. Finally we construct a pro-22 group which satisfies the weak Massey vanishing property for every n3n\geq3, but does not satisfy the strong Massey vanishing property for n=4n=4.
