泊松流形与雅可比流形德拉姆上同调的运算

Operations on the de Rham cohomology of Poisson and Jacobi manifolds

Ai Guan, Fernando Muro

AI总结:

本研究证明泊松与雅可比流形德拉姆上同调的(同伦)超交换代数结构同伦平凡,仅保留通用的(同伦)交换代数结构,并将类似结论推广至广义泊松超流形的交换Batalin-Vilkovisky-∞代数结构。

摘要:

我们证明,由多位学者定义的、泊松流形或雅可比流形德拉姆上同调上的(同伦)超交换代数结构是(同伦地)平凡的,即它可约化为底层的(同伦)交换代数结构。我们通过证明如下结论得到该结果:由外积以及与结构多向量场的内积生成的、编码泊松流形与雅可比流形德拉姆复形上代数结构的DG operad(微分分次 operad),与交换子operad拟同构。因此,这类流形的德拉姆上同调不可能具备任何超出众所周知的(同伦)交换代数结构之外的(高阶)结构,而该结构对任意光滑流形都存在。我们对广义泊松超流形德拉姆复形上的交换Batalin-Vilkovisky-∞代数结构也采用了类似的处理方式。

英文摘要:

We prove that the (homotopy) hypercommutative algebra structure on the de Rham cohomology of a Poisson or Jacobi manifold defined by several authors is (homotopically) trivial, i.e. it reduces to the underlying (homotopy) commutative algebra structure. We do so by showing that the DG operads which codify the algebraic structure on the de Rham complex of Poisson and Jacobi manifolds, generated by the exterior product and the interior products with the structure polyvector fields, are quasi-isomorphic to the commutative suboperad. Hence, there is no hope to endow the de Rham cohomology of such manifolds with any (higher) structure beyond the well-known (homotopy) commutative algebra structure, which exists for any smooth manifold. We proceed similarly with the commutative Batalin-Vilkovisky-infinity algebra structure on the de Rham complex of a generalized Poisson supermanifold.
