Sketch of Lagrangian Formalism,ional Euclidean space equipped with a Cartesian coordinate system. When equations can be supplemented by initial conditions that guarantee a unique solution, we say that the equations admit formulation of the .. Using this terminology, a normal system admits formulation of the Cauchy problem.

https://doi.org/10.1007/978-3-322-89647-6Modern particle and field theories often involve auxiliary variables which have no direct physical meaning. We have seen examples of this kind at the end of first chapter: Lagrangian multipliers for holonomic constraints, forceless Hertz mechanics, electrodynamics and the relativistic particle.
