摘要
This paper is devoted to the one-loop calculation of the fermion Green function in QED within theframework of the minimal quantization method, based on an explicit solution of the constraint equations and the gaugc-invariance principle. The relativistic invariant expression for the fermion Green function with correct analytical propertiesis obtained.
