Our study covers the cases of electromagnetism and Yang-Mills fields and sheds light on some aspects of the Faddeev-Popov method, for both the covariant and noncovariant approaches, which have not been fully clarified in the literature.8 p.application/pdfeng(c) The American Physical Society, 1993Mecànica quànticaTeoria de camps (Física)Partícules (Matèria)Relativitat especial (Física)Quantum theoryField theory (Physics)Special relativity (Physics)info:eu-repo/semantics/article508065info:eu-repo/semantics/openAccess
