摘要

摘要证明了在具有阿贝尔复结构的幂零流形上，存在一个经典构造的非平凡全纯泊松结构。我们确定了它的相关上同调同构于与平凡（零）全纯泊松结构相关的上同调的充要条件。我们还确定了这个同构在Gerstenhaber代数水平上的一个充分条件。

Algebraic Structure of Holomorphic Poisson Cohomology on Nilmanifolds

Abstract It is proved that on nilmanifolds with abelian complex structure, there exists a canonically constructed non-trivial holomorphic Poisson structure.We identify the necessary and sufficient condition for its associated cohomology to be isomorphic to the cohomology associated to trivial (zero) holomorphic Poisson structure. We also identify a sufficient condition for this isomorphism to be at the level of Gerstenhaber algebras.
