设p为素数。我们证明了:对于pro-p分圆特征具有挠自由象的极大pro-p生成的极大pro-p伽罗瓦群,Efrat的初等型猜想的正解蕴含着Mina-tán的Massey消失猜想的加强版本的正解.因此,一个域K的极大pro-p伽罗瓦群包含一个p阶根1(如果p= 2,也是− 1),在几个相关的情况下,对于每个n> 2,它满足强n-Massey消失性质(这等价于对于每个n> 2,杯定义的n-Massey乘积性质,如Minais-Tân所定义的)。
Let p be a prime. We prove that a positive solution to Efrat's Elementary Type Conjecture implies a positive solution to a strengthened version of Minač–Tân's Massey Vanishing Conjecture in the case of finitely generated maximal pro-p Galois groups whose pro-p cyclotomic character has torsion-free image. Consequently, the maximal pro-p Galois group of a field K containing a root of 1 of order p (and also− 1 if p= 2) satisfies the strong n-Massey vanishing property for every n> 2 (which is equivalent to the cup-defining n-Massey product property for every n> 2, as defined by Minač–Tân) in several relevant cases.
