It begins with an analysis of Noether’s theorem, which relates symmetries to conserved quantities, and the mathematical description of these symmetries through group theory. From there, the application of functional integrals is explored to generalize Noether’s theorem to the quantum context, as well as the introduction of generalized symmetries in field theories. Finally, the study delves into quantum anomalies, focusing on chiral anomalies and the techniques developed to address with symmetry-breaking phenomena, such as the Fujikawa method.Attribution-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nd/3.0/br/SimetriasTeoria de camposSimetrias generalizadasTeorema de NoetherAnomaliasSimetriesField theoryGeneralized symmetriesNoether theoremAnomaliesbachelorThesisCNPQ::CIENCIAS EXATAS E DA TERRA::FISICA::FISICA DAS PARTICULAS ELEMENTARES E CAMPOS::TEORIA GERAL DE PARTICULAS E CAMPOS
