约束系统正则形式的广义Ward恒等式及其应用

Generalized Ward Identities in Canonical Formalism for the Constrained System and Their Applications

从约束Ｈａｍｉｌｔｂｎ系统在相空间中的Ｇｒｅｅｎ函数的生成泛函出发，导出了该系统在相空间中的广义Ｗａｒｄ恒等式；给出了它在ＱＥＤ和ｑｕａｒｋ－单胶子系统中的应用；并与其他结果做了比较，文［４］中忽略了对约束的分析和处理，本文则从另一个角度作了补充论证．

Starting from generating functional of Green function in phase space for a constrained Hamiltonian system. the generalized Ward identities in phase space for such system was deduced. The application of this identities to the QED and quark-gluon system were given. the results comparison with other conclusions were discussed. The treatment of constraints had been ignored by some authors. the supplementary proof was presented here in another point of view.
