In this paper, the authors present and compare different Lagrangian reduction procedures: Euler-Poincaré reduction by the whole group and reduction by stages in different orders or using different connections. The exposition keeps track of the equivalence of equations as well as corresponding conservation laws.engjournal articlehttps://doi.org/10.1142/S0129055X22300060https://www.worldscientific.com/doi/10.1142/S0129055X22300060open access517.938Rigid bodyRotorsReduction by stagesLagrange Poincaré categoryFísica-Modelos matemáticosFísica matemática
