It is concluded that the recursive equations for the complete proper solution S can be solved at any order of perturbation theory. If certain conditions on the classical action and on the gauge generators are imposed the solution can be taken local.21 p.application/pdfeng(c) American Institute of Physics, 1993Física nuclearFísica matemàticaPertorbació (Matemàtica)Camps de galga (Física)Nuclear physicsMathematical physicsPerturbation (Mathematics)Gauge fields (Physics)info:eu-repo/semantics/article75110info:eu-repo/semantics/openAccess
