摘要：
The gap in the mathematical derivation of Noether's theorem, and also of the Ward-Takahashi identities, caused by performing variation before quantization is closed by introduction of variational calculus Sor operator fields. It is demonstrated that both Noether's theorem and the Ward-Takahashi identities retain full validity in quantum field theory.
