This encompasses both the case of symmetry-preserving perturbations of a given system, as well as the generic analysis on the structure of (regular) Lagrangians in order to admit a symmetry algebra belonging to a specific isomorphy class.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttps://doi.org/10.14311/AP.2017.57.0373open access512LagrangianLie point symmetryNoether symmetryPerturbationÁlgebra1201 Álgebra
