摘要:

 基于相空间Green函数的生成泛函,导出了非定域变换下正则形式的Ward恒等式. 用于非Abel Chern-Simons(CS)理论,得到了正规顶角间的一些关系式.这里给出的形式的显著优点在于勿需作出相空间生成泛函中对正则动量的路径积分.在非Abel CS理论中的非定域变换下,仅要求LpLgh不变,即可导出正规顶角间的一些关系式.

关键词: 非定域, 正则, Ward恒等式.

Abstract:

Based on the phase-space generating functional of Green function, the canonical Ward identities for non-local transformation have been derived. The application of the results to the non-Abelian Chern-Simons theory, the Ward identities for the gauge-ghost field proper vertices have been also deduced. The significant advantage of our formulation in that one does not need to carry out the integration over canonical momenta in generating functional and one only requives the Lp and Lgh to be invariant under the non-local transformation in non-Abelian Chern-Simons theory.

Key words: Wardidentities, Greenfunction, Phasespace.
