有效Batalin-Vilkovisky理论、等变构形空间和循环链

Effective Batalin--Vilkovisky theories, equivariant configuration spaces and cyclic chains

Alberto S. Cattaneo, Giovanni Felder

摘要:

Kontsevich的形式定理指出流形M上的多重微分算子的微分分次李代数是L-无穷-拟同构于它的上同调。利用上半平面上点的位形空间上的微分形式的积分,给出了L-无穷映射的构造。在这里,我们考虑的配置空间的点在磁盘和工作等价的旋转群。这导致考虑微分分次李代数的多向量场赋予一个发散算子。在R^d具有标准体积形式的情况下,我们得到了这个微分分次李代数上的模从函数代数的循环链到多向量域的L-无穷态射。作为第一个应用,我们给出了与幺模泊松结构相关联的星积函数代数上的迹的构造。的建设是基于Batalin-Vilkovisky量化的泊松西格玛模型的磁盘上,特别是其零模式的治疗。

英文摘要:

Kontsevich's formality theorem states that the differential graded Lie algebra of multidifferential operators on a manifold M is L-infinity-quasi-isomorphic to its cohomology. The construction of the L-infinity map is given in terms of integrals of differential forms on configuration spaces of points in the upper half-plane. Here we consider configuration spaces of points in the disk and work equivariantly with respect to the rotation group. This leads to considering the differential graded Lie algebra of multivector fields endowed with a divergence operator. In the case of R^d with standard volume form, we obtain an L-infinity morphism of modules over this differential graded Lie algebra from cyclic chains of the algebra of functions to multivector fields. As a first application we give a construction of traces on algebras of functions with star-products associated with unimodular Poisson structures. The construction is based on the Batalin--Vilkovisky quantization of the Poisson sigma model on the disk and in particular on the treatment of its zero modes.
