整体共形不变量的分类

A classification of global conformal invariants

Nicolas Boulanger, Jordan François, Serge Lazzarini

摘要:

我们提供了完整的分类,在任意偶数和奇数维,全球共形不变量,即,时空度规及其导数中的标量密度在度规的局部外尔重标度下是不变的,可能直到全导数。我们使用上同调的技术,已经被证明有助于在任意维度的Weyl异常的分类。我们遵循的方法是纯粹的代数和借用技术起源于微扰量子场论的地方是至关重要的。

英文摘要:

We provide the full classification, in arbitrary even and odd dimensions, of global conformal invariants, i.e., scalar densities in the spacetime metric and its derivatives that are invariant, possibly up to a total derivative, under local Weyl rescalings of the metric. We use cohomological techniques that have already proved instrumental in the classification of Weyl anomalies in arbitrary dimensions. The approach we follow is purely algebraic and borrows techniques originating from perturbative Quantum Field Theory for which locality is crucial.
