It is shown that the Lagrange's equations for a lagrangian system on a Lie algebroid are obtained as the equations for the critical points of the action functional defined on a Banach manifold of curves. The theory of lagrangian reduction and the relation with the method of Lagrange multipliers are also studied.
Keywords: variational calculus, lagrangian mechanics, Lie algebroids, reduction of dynamical systems, Euler-Poincaré equations, Lagrange-Poincaré equations
