Poisson结构的闭3-形式变形

Deformations of Poisson structures by closed 3-forms

O. I. Mokhov

摘要:

证明了任意Poisson结构Ω ^{ij}(u)和任意闭3-形式T_{ijk}(u)在相应的闭路空间上生成局部Poisson结构A^{ij}(u,u_x)= M^i_s(u,u_x)omega^{sj}(u),其中M^i_s(u,u_x)(delta^s_j + omega^{sp}(u)T_{pjk}(u)u^k_x)= delta^i_j.利用任意闭3-形式T_{ijk}(u),我们还得到了任意Poisson结构Ω ^{ij}(u)的一个特殊的分次ε-形变.

英文摘要:

We prove that an arbitrary Poisson structure omega^{ij}(u) and an arbitrary closed 3-form T_{ijk}(u) generate the local Poisson structure A^{ij}(u,u_x) = M^i_s(u,u_x)omega^{sj}(u), where M^i_s(u,u_x)(delta^s_j + omega^{sp}(u)T_{pjk}(u)u^k_x) = delta^i_j, on the corresponding loop space. We obtain also a special graded epsilon-deformation of an arbitrary Poisson structure omega^{ij}(u) by means of an arbitrary closed 3-form T_{ijk}(u).
