摘要:

我们提出了一种基于超几何的一般维度下流代数理论的新统一表述。我们以 QP-流形,即微分分次(dg)辛流形,作为基础框架。流代数中的泊松括号是由上述 QP 结构诱导的分次泊松结构的所谓导出括号构造的。通过对 QP-流形进行正则变换,推导出了物理理论中正确的反常项。基于上述结构,构造了一大类包含和不包含反常项(中心扩张)的流代数。此外,利用该表述,系统地获得了与高阶结构相关的一类新流代数。

英文摘要:

We propose a new unified formulation of the current algebra theory in general dimensions in terms of supergeometry. We take a QP-manifold, i.e. a differential graded (dg) symplectic manifold, as a fundamental framework. A Poisson bracket in a current algebra is constructed by the so called derived bracket of the graded Poisson structure induced from the above QP-structure. By taking a canonical transformation on a QP-manifold, correct anomalous terms in physical theories are derived. A large class of current algebras with and without anomalous terms (central extensions) are constructed from the above structure. Moreover, using this formulation, a new class of current algebras related higher structures are systematically obtained.
