Perturbation theory and locality in the Field-Antifield formalism Gomis Torné, Joaquim París, Jordi Física nuclear Física matemàtica Pertorbació (Matemàtica) Camps de galga (Física) Nuclear physics Mathematical physics Perturbation (Mathematics) Gauge fields (Physics) The BatalinVilkovisky formalism is studied in the framework of perturbation theory by analyzing the antibracket BecchiRouetStoraTyutin (BRST) cohomology of the proper solution S0. 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. 2012-04-26T10:18:07Z 2012-04-26T10:18:07Z 1993 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document proporcionada per AIP i http://dx.doi.org/10.1063/1.530407 Journal of Mathematical Physics, 1993, vol. 34, p. 2132 http://dx.doi.org/10.1063/1.530407 (c) American Institute of Physics, 1993 info:eu-repo/semantics/openAccess American Institute of Physics Articles publicats en revistes (Física Quàntica i Astrofísica)
