论文摘要
我们表明，在非亚洲自由群体的界面共同体中，当第二个因素由可分解的准杂态串联表示时，Massey Triple产品始终是微不足道的。我们还表明，在负弯曲的紧凑型riemannian歧管的有界的同胞中，当第二个因子以精确的差分形式表示时，梅西三重产物总是很琐碎的。
We show that in the bounded cohomology of non-abelian free groups the Massey triple product is always trivial when the second factor is represented by the coboundary of a decomposable quasi-morphism. We also show that in the bounded cohomology of a negatively curved compact Riemannian manifold the Massey triple product is always trivial when the second factor is represented by an exact differential form.
