Noether定理的推广及应用

A Generalization of the Noether Theorem and Its Applications

给出了非定域变换下的广义Ｎｏｅｔｈｅｒ恒等式（广义Ｎｏｅｔｈｅｒ第二定理）．将其应用于规范场理论，导出了新的ＰＢＲＳＴ荷和“非定域”荷。

The generalized Noether identities (generalized second Noether theorem)for a dynamic system under non-local transformation are derived in this paper.Applying the theory to gauge fields, the new conservative PBRST charge and other charges connected with non-local transformation are obtained.
