BRST微分方程的Maurer-Cartan结构

The Maurer-Cartan structure of BRST differential

Jining Gao

摘要:

在本文中,我们构造了一个新的序列的生成器的BRST复杂和重新制定的BRST微分,使其作用于元素的复杂的很像Maurer-Cartan微分作用于左不变形式。因此,我们的BRST微分形式上类似于李代数的Chevalley-Eilenberg上链复形的BRST公式中定义的微分。此外,对于一类重要的物理理论,我们证明了微分实际上是Chevalley-Eilenberg微分。作为我们的形式主义的应用之一,我们表明,BRST微分提供了一种机制,使我们能够扩展一个非可积系统的向量场流形上的一个可积系统的扩展流形。

英文摘要:

In this paper, we construct a new sequence of generators of the BRST complex and reformulate the BRST differential so that it acts on elements of the complex much like the Maurer-Cartan differential acts on left-invariant forms. Thus our BRST differential is formally analogous to the differential defined on the BRST formulation of the Chevalley-Eilenberg cochain complex of a Lie algebra. Moreover, for an important class of physical theories, we show that in fact the differential is a Chevalley-Eilenberg differential. As one of the applications of our formalism, we show that the BRST differential provides a mechanism which permits us to extend a nonintegrable system of vector fields on a manifold to an integrable system on an extended manifold.
